[摘要]在某高層剪力墻約束邊緣構(gòu)件設計中,根據(jù)美國UB-97規(guī)范的設計方法,并結(jié)合我國規(guī)范的有關(guān)規(guī)定,以大震作用下結(jié)構(gòu)頂點的最大彈塑性位移為目標位移,確定墻肢的變形能力要求,進而采取與其變形能力要求相一致的抗震構(gòu)造措施。
[關(guān)鍵詞]約束邊緣構(gòu)件;頂點位移;目標位移;壓應變

Abstract:In the design of the confined boundary zones of a-tall shear wall structure, according to the UBC-97, combined with Chinese code, the target displacement can be measured by maximum elastic-plastic displacement of the top of structure under strong earthquakes.The deformation capacity of the coupling wall-column is defined.The details of seismic design agreed with its deformation capacity are adopted.
Keywords:confined boundary zones; top displacement; target displacement; compressive strain
