摘要
文章分析了撬力作用产生的原因,通过对国内外钢结构节点端板厚度设计中采用的对撬力作用计算和设计方法的比较,提出端板厚度计算过程中考虑计算撬力作用更合理,并指出GB 50017-2003中端板厚度计算没有考虑撬力实际大小,过于保守。
In this paper the reason of prying action are discussed.By comparing the difference on prying force calculation with foreign design codes,it is reasonable that prying force should be calculated when designing end-plate thickness.In GB 50017-2003,it doesn t calculate the actual prying force in formula for thickness of endplate,and it is also conservative.
