摘　　要：在输电线路铁塔设计中,经常使用实腹式双拼、四拼组合角钢构件。该类构件通常须在角钢之间加设填板,从而成为一个实腹式整体构件受力.在目前我国钢结构设计规范及输电线路设计规程中,仅简要地提出了填板设置上的构造要求,而对填板及其螺栓的设计计算、具体布置方式均未作详细说明.本文根据材料力学中的榫栓计算原理,并结合试验研究,整理出一套填板及其螺栓的计算方法,以供工程实践参考.Now the cross-section combined angle steels are widely used in power transmission tower.For working as a solid-web member,a numbers of padding plates should be added between two or four angle steels.But in the steel structure design code and specification of China,there is no detail requirement on calculation and arrangement of padding plates and bolts.For the sake of project application,the ways and means about padding plates design are proposed according to principles of mechanics of materials;and that ar...
