输电塔圆钢管相贯节点强度分析

【摘要】 介绍了某大跨越输电塔的节点强度试验概况,着重选取一典型的平面K型相贯节点进行试验数据分析及有限元计算,从而检验了设计的准确性和构造的合理性,并指出了相贯节点的鞍点、冠点以及与节点板连接处均存在的应力集中现象,以供实际工程设计参考。更多还原

【Abstract】 The experiment of joint intensity for a long-span transmission tower is introduced.Experimental results are studied and finite element models are analyzed for a typical planar steel tubular K-joint.The veracity and the rationality of design are tested.And the stress concentration for saddle points,coronal points and node board area is pointed out,so as to arouse more attention for practical design.更多还原
