摘要
对横向长度等于CECS102:2002中规定的最大温度区段长度的单层多跨变截面门式刚架进行了合理设计,并以之为计算模型,重点分析了柱子高度、屋面坡度和刚架横向跨数等对寒冷地区非采暖门式刚架房屋结构平面内温度作用效应的影响规律,结合变形、内力和应力的分布特点,给出了设计中应该注意的问题和合理建议。
The multi-span portal frames with the maximum length of temperature division according to the rules of CECS102：2002, are well designed to be adopted as the analyzing models. The in-plane temperature effects to the non-heating portal frames in the cold regions are studied with the varieties of column-height, roofing-slope and spans of the frames. Based on the results of horizontal deformations and the distributing characteristics of elements forces and stresses, the noticeable questions and reasonable suggestions are brought forward at last.
