一端固支一端铰支二跨梁屈曲的临界压力

The critical pressure of two spans beams with one end fixed and the other hinge joined

推导出了一端固支一端铰支二跨梁在轴向载荷作用下的临界压力表达式 ,得出了等跨度情况下具体的临界压力计算式。在理论上回答了连续梁临界压力的计算问题 ,具有一定的指导意义。

The formula of critical pressure when the two spans were supported at the middle is deduced, and a specific formula of critical pressure about two equal spans beams is obtained, thus solving the computation problem of continuous critical pressure in theory.
