摘要: 連體結(jié)構(gòu)的受力特點(diǎn)與單體結(jié)構(gòu)相比有明顯的差異,某些特殊連接形式的結(jié)構(gòu)設(shè)計尤其值得探討和研究.以兩個實(shí)際工程案例為依托,針對其剛度不對稱、高位連接、大跨度連接體等特點(diǎn),分析并總結(jié)連體形式的選擇、設(shè)計方法和優(yōu)化加強(qiáng)措施等. 在結(jié)構(gòu)整體作用層面,提出巨型框架簡化概念,并采用水平變形等指標(biāo)評價扭轉(zhuǎn)效應(yīng);在結(jié)構(gòu)受力層面,對大跨度連接體受力、施工模擬、復(fù)雜節(jié)點(diǎn)設(shè)計等若干連體結(jié)構(gòu)設(shè)計關(guān)鍵點(diǎn)進(jìn)行了分析,并提出了對策.

Abstract: The force characteristics of the connected structure are obviously different from those of the single structure, andthe structural design of some special connection forms is particularly worth exploring and studying. Based on two practicalengineering cases, according to the characteristics of asymmetric stiffness, high connection and large span connection, theselection of connection form, design method and optimization strengthening measures were analyzed and summarized. At theoverall action level of the structure, the concept of mega?frame simplification was proposed, and the torsion effect wasevaluated by indicators such as horizontal deformation. At the structural force level, several key points of connectionstructure design were analyzed such as the force of large span connection, construction simulation and complex nodedesign, and the countermeasures were put forward.
Keywords:connected structure; large span structure; high?rise building; seismic performance; asymmetric structure
