[摘要] 全鋼框架結(jié)構(gòu)中設(shè)置偏心支撐的結(jié)構(gòu)體系比較適用于抗震設(shè)防高烈度區(qū)，但受業(yè)主的傳統(tǒng)認(rèn)識(shí)、防火防腐問(wèn)題和造價(jià)偏高、結(jié)構(gòu)設(shè)計(jì)師的設(shè)計(jì)習(xí)慣等因素的影響，全鋼結(jié)構(gòu)房屋的應(yīng)用受到一定程度限制。某高烈度區(qū)高層停車樓，采用了鋼結(jié)構(gòu)偏心支撐（消能梁為鋼梁）+鋼筋混凝土框架結(jié)構(gòu)體系，對(duì)其進(jìn)行靜力彈塑性推覆分析，表明這種混合體系有較好的抗震性能，對(duì)于高烈度區(qū)的多層或高度偏低的高層建筑，具有很好的適用性。

Abstract: All-steel-structural frame set eccentrically braced structural systems are more suitable for buildings in the zone of lugh seisnuc precautionary intensity. But by impact of traditional knowledge of the owners, fire anti-corrosion problems, the high cost, and the engineers' design habits and other factors, the application of all-steel-structural building has been somewhat limited. However, the system of steel eccentric bracing( the energy dissipation beam is steel)  and reinforced concrete frame, which is applied in a high-rise parking building on the zone of high seismic precautionary intensity that through the static elastic-plastic Pushover analysis of wluch to reveal good seismic performance of this hybrid structural system, is proved to be very suitable for multi-storey or low-side high-rise buildings on such zone.
Keywords: eccentric bracing; frame structure; Pushover analysis; high intensity area
