［摘要］斜交網(wǎng)格體系通過(guò)斜柱軸力來(lái)承受整體結(jié)構(gòu)的水平作用力，具有較大的抗側(cè)剛度。首先簡(jiǎn)單介紹了斜交網(wǎng)格體系的基本形式；接著通過(guò)系統(tǒng)的參數(shù)化分析，研究不同斜交角度、高寬比、平面形狀和立面變化等主要因素對(duì)斜交網(wǎng)格體系的整體抗側(cè)剛度、傾覆力矩以及構(gòu)件內(nèi)力的影響。結(jié)果表明：斜交角度對(duì)斜交體系的抗側(cè)性能影響較大，存在最優(yōu)的斜交角度以使得整體結(jié)構(gòu)抗側(cè)剛度最大；高寬比的影響也較大，隨高寬比的增大，結(jié)構(gòu)頂部水平位移逐漸增大，且增大趨勢(shì)逐漸加快，風(fēng)載作用下尤為明顯；不同平面形狀和立面變化對(duì)結(jié)構(gòu)抗側(cè)性能的影響相對(duì)較小。

Abstract:The oblique grid system bears the horizontal force of the whole structure through the axial force of the inclined column, which has a large lateral stiffness. Firstly, the basic form of oblique grid system was introduced briefly; secondly, according to the systematic parametric analysis, the influences of  the main influencing factors such as different oblique angles, height width ratio, plane shape and facade changes on the overall lateral stiffness, overturning moment  of oblique grid system and internal force of components were carried out. The results show that the oblique angle has a great influence on the lateral resistance of the oblique system, and there is an optimal oblique angle to maximize the lateral stiffness of the whole structure; the height width ratio also has a great influence, and the horizontal displacement at the top of the structure gradually increases with the increase of the height width ratio, and the increasing trend is gradually accelerated, especially under the action of wind load; the influence of different plane shapes and facade changes on the lateral resistance of the structure is relatively small.

Keywords:oblique grid system; oblique angle; facade change; lateral stiffness; overturning moment
