In the model, Wi is rigidly fastened to the tank walls at a height hi above the tank bottom, which corresponds to the location of the resultant impulsive force Pi.

Zci differences between the UBC and the IBC seismic provisions wci used in this Standard are primarily due to differences in the definition of design ground motions and the construction of the corresponding design response spectra as explained below.

When using preformed slots, vertical bending moments induced in the wall by shear should be considered. Engineering judgment may require a factor I greater than tabulated in Table 4. Overturning moments—Compute overturning moments for the lateral loads described above using the procedures of Section 4. ACI and its members disclaim liability for damages of any kind, including any special, indirect, incidental, or consequential damages, including without limitation, lost revenues or lost profits, which may result from the use of this publication.

Where overtopping is tolerable, no accommodated shall be calculated from the following freeboard provision is necessary. The profile of the response spectrum is defined by Sa, which is a function of the period of vibration and the mapped accelerations SS and S1 as described in Section R9. The user must determine the applicability of all regulatory limitations before applying the document and must comply with all applicable laws and regula- tions, including but not limited to, United States Occupational Safety and Health Administration OSHA health and safety sci.

Thus, it cannot present background details or suggestions for carrying out its requirements or intent.

In rectangular tanks, calculate the stresses in the wall due to the impulsive and convective pressures, depending on the structural system considered Section 6.

Tv Therefore, for rectangular tanks, Ct is taken independent of the period of vibration. Using the frequency values determined in Steps 8 and 9, calculate the corresponding natural periods of vibration Ti and Tc. Dhingra Dov Kaminetzky Lawrence G.

A plot of the seismic response coefficient Ci is shown in the design response spectrum in Fig. Normally, this is smaller than the 350-6 effect, but if there is not enough dead load, the tank will tend to uplift.

Downward pressures on the neoprene bearing pads of free base circular tanks caused by overturning moments should be considered.

The following equations are provided as examples for the special case of a wall of uniform thickness. For tanks with roof overhangs, the concrete lip can be designed to withstand the earthquake force.

For liquid-containing structures, this standard uses the static procedures in accordance with This standard includes the effects of vertical acceleration; and The user should note the following general design methods 5.

The convective pressures are those produced by the oscillations of the fluid and are therefore the consequences of the impulsive pressures.

English Choose a language for shopping. For all seismic zones: Based on the natural periods determined in Step 10 and the design spectral response acceleration values derived in Step 2, calcu- late the corresponding seismic response coefficients Ci and Cc Eq.

AmazonGlobal Ship Orders Internationally. Where applicable, the lateral forces due to the dynamic earth and groundwater pressures against the buried portion of the walls shall be computed in accordance with the provisions of Chapter 8. Welding of reinforcement is covered by reference to the appropriate AWS ai.

ACI committee documents are intended for the use of individuals who are competent to evaluate the significance and limitations of its content and recommendations and who will accept responsibility for the application of the material it contains. For explanation, refer to Housner []. In general, the wall-footing interface should have reinforcement designed to transmit these shears through the joint.
