摘要
针对某网架模型竖向承载力试验,提出一种由滑轮和绳索组成的新型加载系统。克服了传统分配梁加载体系的种种缺点,揭示了该加载系统的拉力损失机理,总结出减少拉力损失的方法,并有效地应用在试验中。
A new type of loading system including puileys and ropes was developed in the ultimate load capacity test of a space truss model.The innovative loading system of ercomed the defects the traditional loading method possessing.The tension loss mechanism existing in this loading system was analyzed in detail.According to the analysis result,a reliable installation was used in the experiment.
