【摘要】 本文着重论述了网架结构弹性边界的处理 ,提出了以构件代替弹性支座的合理方法 ,针对不同的支撑情况 ,推导出了弹性支座的刚度系数计算公式。经实例分析证明了该方法的准确性 ,其计算结果更靠近结构的真实受力性能 ,在钢结构设计软件XJDST中得以实现更多还原

【Abstract】 The thesis have discussed the elastic boundary condition of space frame,give a reason method which use a member replaced the elastic support,the formula of elasticity modulus are presented,from the example,we have proved the veracity of the method.The result is closely to the real stand force capability,and come true in the steel design software—XJDST. \[更多还原
