固定式起重机荷载作用下扶壁码头结构内力计算研究

摘要

为了研究在固定式起重机荷载作用下的扶壁式码头结构内力计算方法,文章使用ANSYS建立了三维有限元模型,利用有限元模型计算出扶壁结构立板和底板应力,进而计算出板的弯矩.将立板与底板弯矩和规范计算值对比,根据有限元模型计算结果,对立板和底板不同方向的弯矩提出了新的简化计算模型.在固定式起重机荷载作用下,立板与底板的内力与规范的计算方法差距较大,而采用文章中提出的新的简化计算模型差距较小.%In order to research the calculation method of structural internal force of the buttressed wharf under the load of the fixed crane, the 3-D finite element model was established in this paper, and the model was used to calculate stress and moment of the vertical plate and the bottom plate.In comparison of the numerical simulation re-sults and code calculation, several new simplified calculation models were proposed.Under the load of fixed crane, moment of the vertical plate and the bottom plate fits these new simplified calculation models, and there is a wide gap between the numerical simulation results and code calculation results.
