［摘要］斜交网格体系通过斜柱轴力来承受整体结构的水平作用力，具有较大的抗侧刚度。首先简单介绍了斜交网格体系的基本形式；接着通过系统的参数化分析，研究不同斜交角度、高宽比、平面形状和立面变化等主要因素对斜交网格体系的整体抗侧刚度、倾覆力矩以及构件内力的影响。结果表明：斜交角度对斜交体系的抗侧性能影响较大，存在最优的斜交角度以使得整体结构抗侧刚度最大；高宽比的影响也较大，随高宽比的增大，结构顶部水平位移逐渐增大，且增大趋势逐渐加快，风载作用下尤为明显；不同平面形状和立面变化对结构抗侧性能的影响相对较小。

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
