摘要: 鄭州國際文化交流中心酒店地上 9 層,地下 2 層,地上分為 A 區(qū)、B 區(qū)兩個結(jié)構(gòu)單元,均為復(fù)雜超限高層建筑.主體結(jié)構(gòu)均采用鋼筋混凝土框架-剪力墻體系,關(guān)鍵部位采用型鋼混凝土或全鋼結(jié)構(gòu). A 區(qū)有跨度為 23. 7~ 25. 3m 的弧形轉(zhuǎn)換,采用弧形型鋼混凝土轉(zhuǎn)換梁;B 區(qū)在 3 層~屋面有 11. 3m 的超長懸挑,采用雙層斜拉桿體系. 分析了結(jié)構(gòu)整體性能,明確了結(jié)構(gòu)關(guān)鍵部位,選取并驗(yàn)證了中震、大震下的性能化目標(biāo),采用大震彈塑性時(shí)程分析揭示了結(jié)構(gòu)薄弱部位并采取了針對性措施. 專項(xiàng)分析了弧形轉(zhuǎn)換梁的抗扭能力和應(yīng)力分布,超長懸挑區(qū)的樓板作用、節(jié)點(diǎn)應(yīng)力、抗連續(xù)倒塌能力,并提出了加強(qiáng)措施. 分析結(jié)果表明,結(jié)構(gòu)設(shè)計(jì)滿足規(guī)范要求,并具有良好的抗震性能.

Abstract: The hotel in Zhengzhou International Cultural Exchange Center has 9 floors aboveground and 2 floorsunderground. The aboveground building is divided into two structural units, zone A and zone B, both of which belong tocomplex out-of-code high-rise building. The main structure adopts the reinforced concrete frame-shear wall structure, andthe key parts adopt steel reinforced concrete or all steel structure, zone A has 23. 7~ 25. 3m large-span arc-shaped transfer,which adopts arc-shaped steel reinforced concrete transfer beam. Zone B has 11. 3m super-long cantilever on the third floorto the roof, which adopts double-layer tie rod system. The overall performance of the structure was analyzed, the key partsof the structure was defined, the performance-based target under medium and large earthquakes were selected and verified,the weak parts of the structure were revealed by large earthquake elastic-plastic analysis, and targeted measures were taken.The torsional capacity and stress distribution of the arc-shaped transfer beam, the floor action and the joint stress andresistance to progressive collapse in the cantilever area were specially analyzed,and strengthening measures were proposed.The analysis results show that the structural design meets the requirements of the code and has good seismic performance.
