| 摘 要： | 近年来有不少文献提出了关于两梯段折板式悬挑楼梯(结构对称,受对称荷载的情况)的计算方法,如文献[1]、[2]、[3]等等,但所解决的问题都有一定的局限性。本文提出了用力法解算悬梯平面转角为任意角度时的计算方法,并具有下列特点:(1) 在计算力法方程中的系数和自由项时有选择地保留了影响较大的各项。这样既使计算达到一定的精度,又使计算得到简化;(2) 用扇形面代替折角形休息平台,这样的计算简图更接近于实际情况;(3) 考虑了平台荷载的偏心。

| Abstract: | The analysis of two flight free standing staircase has been presented inmany papers recently. However, the solution of the problem has certainlimitations. In this paper, an analysis with force method is presented whenthe angle of rotation of stair plane is arbitrary. It possesses the followingfeatures: (1) in the computation of the coefficients and the free terms inthe equations of force method, the terms which produce greater influence areselectively remained, so that the computation reaches certain accuracy and atthe same time has been simplified; (2) the intermedia'e polygon platform isreplaced by a sector, so that the scheme it more reliable; (3) the eccent, icityof platform loading has been considered. |
