港工码头上使用的钢筋混凝土空心板一般属于厚板,这种空心厚板除受布满全板的均布面荷载或受垂直于板跨方向的均布线荷载作用,可简化为梁条计算外,在其它荷载作用下没有理论解。用有限元法分析时,宜采用空间等参单元,不宜采用薄板单元。但通常由于位移参数多、劲阵阶数高,因而应用中小型计算机计算就难以实现。
The reinforced concrete hollow slabs used on port workers are generally thick slabs. This kind of hollow slabs can be simplified as beam calculations, except for the uniform surface loading of the full slab or the uniform wiring load perpendicular to the slab span direction. In addition, there is no theoretical solution under other loads. When using the finite element method for analysis, space isoparametric elements should be used, and thin plate elements should not be used. However, due to the high displacement parameters and the high order of the matrix, the application of small and medium-sized computer calculations is difficult to achieve.
