摘要:
本文利用加权余量法推导出狭长矩形截面简支梁在纯弯曲时,发生弹性失稳的临界弯矩Mor计算式.
Abstract:
Elastic instability may occur when a simple supported beam with nar- rower rectangular section is snbjected to pure plane bending.For calculating its critical bending moment(Mcr),a formula is derived by weighted residual met- hod in this paper.
