摘要
本文介绍了杆件抗扭强度条件和刚度条件的控制计算方法,并分别对开闭口型材断面进行抗弯承载对比,进而详细分析了杆件的实际受力状况,说明一般框支撑玻璃幕墙设计时,无须进行横杆抗扭校核;但是对螺杆孔壁局部承压变形分析后,提出杆件必须进行抗倾覆校核。
The author introduced the ways to calculate the strength and stiffness about torsion for rail, contrasted close rail to open rail about bending strength, then explained that the torsion have not to be considered in the designs of frame supported curtain wall through analysising the status format of rail, but the check of capsizal is necessary because of the screw hole＇s distortion.
