静不定平面桁架结构杆元内力简化分析

The Simplex Analysis for the Internal Force of the Membersof the Statical Indeterminate Planar Truss Structure

叙述静不定平面桁架结构零杆判别定理,以及数根杆元交汇于受力结点,杆元内力矩阵简化分析。具有一定理论意义和实用价值。

This paper relates the distinguishing theorem about the zero members of the statical indeterminate planar truss structure, and simplex analysis for the internal force matrix of the loading joint collecting many bars. It gives important theoretical meaning and practical value.
