The following sections give normally permissible deflection limits for steel and concrete structures.

The functional requirements of the structure may impose stricter limits. Systems should be reviewed for possible incompatible deflection behavior in piping, equipment or building components and support deflections.

Beam Deflections (Based on Live Loads Only)

Maximum allowable deflection for beams supporting floor systems and equipment shall be as follows:

Max deflection = L / 500 L = Span

Maximum allowable deflection for beams supporting brittle finishes such as plaster ceilings shall be as follows:

Max deflection = L / 360 L = Span

Maximum allowable deflection for purlins supporting roof system shall be as follows

Max deflection = L / 400 L = Span

Maximum allowable deflection for cantilever beams shall be as follows:

Max deflection = L / 400 L = Overhang Length

Maximum allowable deflection for beams supporting steel platforms, staircases, pipe racks, etc.

Max deflection = L / 300 L = Span

Crane Runways

Max deflection = L / 300 L = Span

Overhead Traveling

Max deflection = L / 600 L = Span

Monorails

Max deflection = L / 400 L = Span

h = height of story or height of structure

These limits apply to sway between stories and to the structure as a whole.

Grating = L / 250 (Maximum span 1.6 meter)

Vibration

Superstructure Vibration

The primary source of vibration in superstructures is harmonic unbalanced forces generated by rotating or reciprocating equipment. The final design should be such that vibrations will be neither intolerable nor troublesome to personnel and not cause damage to the machine or structure or adjacent foundations, structures or services.

As a general rule, none of the natural frequencies of the structure should be within a band of the operating frequency of the supported machinery. The band recommended to be avoided is 1.414 above operating frequency and 0.707 below operating frequency. To find structural natural frequencies, a computer analysis shall be required.

All natural frequencies below 2 times the operating frequency for reciprocating equipment and below 1.5 times the operating frequency for rotating equipment shall be calculated.

It shall be demonstrated that the amplitudes at the natural frequencies between 0.35 and 1.5 times the operating frequency are within the allowable values even assuming that, due to differences between the actual structure and the assumed model, resonance does occur. In this case a reasonable amount of damping should be estimated.

Resonance condition requires a detailed three dimensional dynamic analysis. Once a model analysis has been conducted, a harmonic response analysis shall be performed. The response analysis will indicate anticipated amplitudes of vibration, velocity, and acceleration as well as magnitudes of forces in structural members. From the above information, the adequacy of the design can be evaluated and if necessary, modifications may be made.

The maximum vibration amplitude of the equipment shall not exceed the lower of the following values:

a. The maximum allowable values stated by the manufacturer of the equipment.

b. The amplitude (single amplitude) which causes the effective velocity of vibration to exceed:

2 mm / s at the location of the machine bearing housings

2.5 mm / s at any location of the structure

c. The dynamic amplitude of any part of the foundation including any reciprocating compressor shall be less than 80 µm single amplitude (80 x 10^-3mm).

The effective velocity is defined as the square root of the average of the square of the velocity, velocity being a function of time. In the case of a pure sinusoidal function the effective velocity is 0.71 times the peak value of the velocity.

The depth of a steel beam supporting large open floor areas free of partitions or other sources of damping should not be less than 1/20 of the span to minimize perceptible transient vibration due to pedestrian traffic.
Foundation Vibration

The Designer shall determine which vibrating equipment is to be analyzed by dynamic analysis.


Dynamic Analysis

For foundations for reciprocating machinery, centrifugal machinery and centrifugal pumps 750 kW or over, a three dimensional dynamic analysis must be performed. Foundation vibration generally involves a grade foundation designed to support one or more reciprocating or rotating machines.

Generally the same considerations for superstructure vibration also apply to foundation vibration.

The primary differences are that these foundations are often rigid blocks and that soil behavior must be considered. Rigid foundations supporting only one major machine can readily be analyzed using hand calculations and the concept of elastic half-space theory. For flexible foundations or foundations with many machines, a computer analysis should be utilized along with the concept of elastic half-space theory. The Designer shall prepare an instruction for foundation vibration analysis which contains current state-of-the-art approaches, soil information, machine information, dynamic analysis aids, published response criteria, example solutions, and a comprehensive list of references.

The dynamic amplitudes of any part of the foundation including any reciprocating compressor shall be less than 80 µm (80 x 10^-3 mm) single amplitude.

For the dynamic analysis, the exciting forces shall be taken as the maximum values that according to the Manufacturer of the equipment will occur during the lifetime of the equipment. When the exciting force is not given by the Manufacturer, it shall be determined from

Q(kN) = [Rotor Speed (rpm)/6000] x Rotor Weight (kN)

The dynamic calculations shall be based on a mechanical model wherein the weights and elasticity of both structure as well as foundation and the weight of the equipment to be represented in an appropriate way.

All natural frequencies below 2 times the operating frequency for reciprocating equipment and below 1.5 times the operating frequency for rotating equipment shall be calculated.

It shall be demonstrated that the amplitude of the natural frequencies between 0.35 and 1.5 times the operating frequency are within the allowable values even assuming that, due to differences between the actual structure and the assumed model, resonance does occur. In this case, a reasonable amount of damping should be estimated.

The natural frequency of the supporting structure shall not coincide with any resonant frequency of the equipment.

The static deformation for rotating equipment foundations shall be calculated and shown to be within the limits stated by the Manufacturer of the equipment. The calculations shall include but not be limited to the following causes of deformation.

Shrinkage and creep of concrete.

Temperature effects caused by radiation and convection of heat or cold generated by machinery, piping, and ducting.

Elastic deformation caused by changing vapor pressure in condensers.

Elastic deformation caused by soil settlement.

Non-Dynamic Analysis

For installations that do not warrant a dynamic analysis, (equipment weight less than 5000 kN), the mass ratio concept is commonly used. In the design of equipment foundations subject to vibratory loading where dynamic analysis is not performed, foundations shall be proportioned as indicated below:

Rotating equipment mass ratio = weight of concrete / weight of machine > 3

Reciprocating equipment mass ratio = weight of concrete / weight of machine > 6

Design flow conditions at the entrance / inlet to the pumping station

The water levels at the pumping station entrance and the approach flow patterns considered in the analysis took account of the flow into Pumping Station. The minimum water level of ‑0.95m NHD corresponds to a head loss of only 0.07m in the channel. Approach flow patterns are direct and well-behaved.


Review of layout in relation to design guidelines, etc.

The typical maximum approach flow velocities to the bar screens are considered to be within acceptable limits in relation to potential turbulence levels at the bar screens.


In the worst case (i.e for PH-) at maximum flow, the velocity in the double-entry channels at the drum screens shall be typically 0.86m / s. This is a little high relative to HR Wallingford's experience of other installations and it would be appropriate to confirm with relevant screen vendors that a maximum approach velocity of some 0.8-0.9m / s is acceptable in the channels approaching the drum screens.
In the worst case (when one screen train is out-of-service), the maximum velocity leaving the screen units shall be approximately 0.8m / s. This is considered a little high in relation to the size of the forebay area, as confirmed by the CFD model. Flow modification measures (e.g. Baffles or columns) are likely to be required in the forebay to ensure satisfactory flow patterns under adverse combinations of screens and pumps in operation.
Submergence of pumps

The available submergence and proposed elevation for the pump bay invert (-9.50m NHD) are considered satisfactory in relation to the required submergence conditions for minimisation of free-surface vortices.


Overall dimensions and internal structures

The proposed overall layout and dimensions for the screen chambers is considered satisfactory for FEED. It would be recommended, however, that the required width of each screen chamber element should be subject to further review / detailed design during EPC - following identification of the actual screen vendor and actual screen dimensions.


In the case of PH#, the initially designed pump chamber width of 5.0m is smaller than standard guidelines would suggest. Preliminary enquiries with pump manufacturers have indicated that a pump chamber width of 5m would be acceptable (even based upon a bell mouth diameter of 2.7m). Taking this into account, the proposed 5m width for each pump chamber is considered satisfactory for FEED. It would be recommended, however, that the required width of each pump bay should be subject to further review / detailed design during EPC - following final confirmation of the actual pump vendor and actual bell mouth diameters.
The Initial Design for the pump bays provides for a “standardised” pump bay length of 10m, which is satisfactory with respect to the pumps for PH and PH but short relative to standard guidelines in the case of PH#.
The proposed “standardised” distance from the rear wall of a pump bay to the pump centre line of 2.2m is in accordance with standard guidelines.
In general terms, the splitter / benching, corner fillets and curtain wall arrangements are considered appropriate vortex suppression devices / methods. On the basis of "standard best practice", it is considered that these features should be included in the pump bays, as they shall help serve to inhibit severe surface and sub-surface vortex formations.
Free passage of air must be allowed at the top of the pump bays and other semi-enclosed areas of the pumping stations.

The roof slab is expected to be clear of the water surface even for extreme water level/wave conditions (notwithstanding possible transient water levels in the Intake Channel that might result from pump start-up or trip scenarios).


The possible improvements identified for testing in the CFD model resulted from the short pump chambers in PH and the restricted distance between the drum screen chambers and the pump chambers.
Computational fluid dynamics (CFD) model tests

Simulations have been undertaken for a variety of operational conditions in the planned Plant CCWS pumping station.


The calculated water level at the entrance to the pumping station takes account of the flow into the Phase I pumping station (PH, and the intake channel model demonstrated well-behaved approach flow to PH and PH. Therefore, although the pumping station computational model does not explicitly simulate PH, the simulations take account of the effect of the flow into PH.
With the original design, and under adverse combinations of pumps and screens in operation, significant oblique flow with local velocities approaching 1m / s was observed in the pump forebays. Flow in the pump chambers under these conditions was asymmetric, locally approaching 0.8m / s and there was rotation at the pumps.
Revisions to the design have been proposed, in which columns are introduced at the entrance to the pump chambers to dissipate the asymmetric jets. Further simulations have been carried out to show the effects on the flow patterns. These show significantly improved flow patterns in the pump chambers, but there is scope for further improvement in the forebays.
The CFD model studies indicate that the overall pumping station dimensions are adequate, subject to provision of the dissipating structures described above and optimised during EPC.
Physical model study

To confirm and extend the conclusions of the CFD model study, it is recommended that a physical model study be carried out during the EPC phase. This would enable final optimisation of the internal layout, and confirmation of satisfactory performance under the final design operating conditions.
