[摘要] 介紹了屈曲約束支撐在上海東方體育中心綜合館中的應(yīng)用。綜合館拱架平面外每側(cè)設(shè)置了三榀大型支撐框架。為滿足建筑對(duì)截面的要求，同時(shí)避免支撐桿件在結(jié)構(gòu)承受水平荷載時(shí)受壓屈曲先于強(qiáng)度屈服，提高支撐框架在罕遇地震中的耗能性能，在豎向支撐框架中采用了屈曲約束支撐。對(duì)結(jié)構(gòu)設(shè)置屈曲約束支撐的優(yōu)點(diǎn)、總體和節(jié)點(diǎn)設(shè)計(jì)方法以及安裝施工手段進(jìn)行了闡述，對(duì)其在結(jié)構(gòu)設(shè)計(jì)中的應(yīng)用和推廣具有現(xiàn)實(shí)意義。

Abstract: The application of buckling restrained braces in Shanghai Oriental Sports Center General Gymnasium was presented. Three large support frameworks were set up on each side of General Gymnasium out of arch plan. To meet the construction requirements of section, avoid supporting bar pieces to be buckling under pressure before strength yield while withstand lateral loads, and improve energy dissipation capacity of the supporting frame in rare earthquake, the buckling restrained braces were used in vertical support framework. The advantage of the buckling restrained braces, design method of integral structure and node, methods of erection construction, were described. There will have practical significance of its application in structural design and promotion.
Keywords: buckling restrained braces; strength yield; rare earthquake; energy dissipation capacity; design method
