[摘要] 天津津塔是一棟高336. 9m的鋼結(jié)構(gòu)超高層建筑，主要抗側(cè)力體系采用“鋼管混凝土柱框架+核心鋼板剪力墻體系+外伸剛臂抗側(cè)力體系”組成。薄鋼板剪力墻結(jié)構(gòu)作為一種新的結(jié)構(gòu)體系，充分利用薄鋼板的拉力場(chǎng)效應(yīng)，具有較大的彈性初始剛度、大變形能力和良好的塑性性能、穩(wěn)定的滯回特性等優(yōu)點(diǎn)，但在國(guó)內(nèi)還沒(méi)有先例。本文針對(duì)鋼板剪力墻建立4個(gè)不同參數(shù)局部模型并采用ANSYS有限元分析軟件進(jìn)行彈塑性分析得出了鋼板剪力墻的力學(xué)性能規(guī)律。

Abstract: Tianjin Jinta is a super high-rise building with 336.9 meters high, the main lateral -resistance system consisting of "concrete - filled steel tube column frame  +  steel plate shear wall core tube  +  outrigger system".  As a new structural system, thin steel plate shear wall structure have greater flexibility in the initial elastic stiffness, better plastic performance and much more stable hysteresis, etc, by making full use of tension field effect. There is no precedent project in China.  Four different parameters of part of real structural models are set up for elastic - plastic analysis of steel plate shear wall mechanical behavior by using ANSYS finite element analysis software.
Keywords: steel plate shear wall; tension field effect; post-buckling strength; elastic-plastic analysis
