Suitable seismic performance objectives were selected for important lateral-resistance components of reinforced concrete-arc columns. Multiple programs were used to analyze and compare to make the structure meet expected seismic performance objectives with good economy, which is the key to the success of the structural design of this engineering.Keywords: reinforced concrete arc column; spatial frame structure; out-of-code structure; oblique roof; two-way orthogonal steel truss作者簡(jiǎn)介:吳中群,學(xué)士,一級(jí)注冊(cè)結(jié)構(gòu)工程師,Email:wzq3161@sina.com。參考文獻(xiàn)[1]GB 50011—2010建筑抗震設(shè)計(jì)規(guī)范[S].北京:中國(guó)建筑工業(yè)出版社,2010.
