【摘要】 大连东港G01地块项目结构高度162.65m,采用框架-核心筒结构,框架柱采用适应建筑立面的内收和外张的斜柱,内收和外张的角度为6.91°,顶部内收角度为12.31°。重点分析了斜柱外框架剪力分布特点。通过对结构进行的性能化分析和大震下的动力弹塑性分析表明,结构具有良好的承载和变形能力。更多还原

【Abstract】 The frame-corewall structure is applied in Donggang G01 project in Dalian with the structural height of 162. 65 meters. To coordinate with the building facade,the frame columns were designed inclined inward and outward with angles of 6. 91 degrees and the top inward angels of 12. 31 degrees. The shear distribution characteristics of the outer frame composed of inclined columns were focused in analysis. The structure shows good bearing capacity and deformation capacity in performance-based seismic design and dynamic elastic-plastic analysis under the rare earthquake.更多还原
