| Abstract | To achieve the objective, a 40-story core walls building is selected as a case study. The building is designated under five different loading conditions: (1) low-level seismic load, (2) moderate-level seismic load, (3) moderate-level wind load, ( 4) a combination of low-level seismic load and moderate-level wind load, and (5) a combination of moderate-level seismic load and moderate-level wind load. The effect of wind resistant design on the seismic design can be determined by comparing the loading demand (e.g. shear and bending moment in the core walls) from these different design cases. In the seismic design, two different design procedures are considered. The first one is the Response Spectrum Analysis (RSA) procedure as stipulated in the 1997 US. Uniform Building Code (UBC97). The second one is the Nonlinear Time History Analysis (NLTHA) procedure. In the wind resistant design, the Architecture Institute of Japan (AIJ) procedure for along wind and across wind loading analysis is adopted. It is found that ( 1 )the RSA procedure is not suitable for the design of high rise buildings because the design demands computed by this procedure are much lower than the true seismic demands estimated by the NLTHA procedure and (2) when the wind load is ยท considered together with low seismic load, the demand from wind load are generally higher than seismic demands computed by the RSA procedure, and hence govern the strength design. However, the true seismic demands as computed by the NLTHA procedure are far greater than wind demands. It is therefore very important to finally check the true demands by the NL THA procedure. |
