［摘要］等腰直角三角形的平面形式因有一些不利的結(jié)構(gòu)特性，在高層建筑中比較少見(jiàn)。以具體工程為例，分析了等腰直角三角形平面的抗側(cè)抗扭不利性，以及高寬比、地震計(jì)算角度的確定方法，并嘗試通過(guò)在三角形平面的角部增設(shè)類角筒來(lái)增加角部抗側(cè)力構(gòu)件的剛度。研究表明，增加外框架的環(huán)向剛度可以提高外框架結(jié)構(gòu)的抗扭性能；通過(guò)調(diào)節(jié)核心筒兩側(cè)墻厚等設(shè)計(jì)及構(gòu)造措施可使等腰直角三角形結(jié)構(gòu)體系趨于更合理。

Abstract:The plane form of isosceles right triangle is rarely used in high\|rise buildings because of  some unfavorable structural characteristics. Taking a an actual project as an example, the disadvantage of lateral torsion resistance, the aspect ratio and the determination method  of seismic calculation angle  of isosceles right triangle plane were analyzed. And the corner tubes were tried to added on the corners of the triangular plane  to increase the stiffness of the lateral resistance components. The results show that the torsion resistance of the outer frame structure can be improved by increasing the circumferential stiffness of the outer frame, and the isosceles right triangle structure system can be more reasonable by adjusting the wall thickness on both sides of the corewall.

Keywords:triangular plane; lateral torsion resistance; aspect ratio; seismic calculation angle
