摘　　要：在保证结构安全和施工简便的前提下,设置百叶外形能够为格构式造型斜柱提供建筑美感,但百叶的长度、间距和倾角均会影响整体结构的风荷载分布以及体型系数。数值模拟结果表明,百叶与下部结构的迎风面位置体型系数最大,随后由中部向两侧方向逐渐减小。百叶设置长度、间距增大时,迎风面的风荷载体型系数呈现减小的趋势,其系数降幅达28%;而百叶设置倾角、厚度的增加会令系数增幅达到30%;因施工误差而导致风荷载体型系数的变化在-10%~+10%。Under the premise of ensuring structural safety and simple construction,setting the louver shape can provide architectural beauty for the lattice-shaped inclined column,but the length,spacing and inclination of the louver will affect the wind load distribution and shape coefficient of the overall structure.The numerical simulation results show that the shape coefficient of the windward side of the louver and the lower structure is the largest,and then gradually decreases from the middle to both sides.When the length and spacing of the louver are increased,the shape coefficient of the wind load on the windward side shows a decreasing trend,and the coefficient decreases by 28%.The increase of the inclination angle and thickness of the louver will increase the coefficient by 30%.The variation range of wind load shape coefficient caused by construction error is within-10%~+10%.
