[提要]  詳細(xì)介紹了一幢體型不規(guī)則和平均高寬比超限的高層結(jié)構(gòu)的設(shè)計(jì)計(jì)算的全過程。針對(duì)平面凹口較深、平面較為狹長、平面寬度變化及高寬比較大等結(jié)構(gòu)特點(diǎn)，在結(jié)構(gòu)布置、分析計(jì)算和構(gòu)造措施等方面作出了有效的處理，使結(jié)構(gòu)的扭轉(zhuǎn)效應(yīng)得到控制，高寬比較大的潛在危險(xiǎn)得以消除，整體設(shè)計(jì)滿足規(guī)范要求。

This paper presents the structure design and computing process of a high-rise building in detail. The building, whose average height-to-width ratio is out of code, has concave trough that breaks through the limit of plane regularity. Through the structure plane arrangement, elastic plane design and the structural treatment for the upper structure, the torsion of the structure is controlled, the risk of the large height-to-width ratio is eliminated, and the code is satisfied. This project can glve reference to the similar design.
Keywords: irregular shape; height-to-width ratio; elastic slab; torsion; structural measures
