【摘要】 以铰接板理论为基础,结合空间梁格法和实体有限元法,对装配式空心板桥荷载横向分布计算方法进行了分析。比较了各计算方法的计算结果之间的差异,阐述了误差产生的原因,探讨了各计算方法的准确性和适用性,并给出了合理的建议。研究结果表明:不考虑边板、中板截面几何特性的差异会导致边板荷载横向分布系数减小而偏不安全;实体有限元法计算结果准确,与之相比,铰接板(梁)法和空间梁格法均存在误差。更多还原

【Abstract】 Based on the hinge-jointed plate theory,combined with space grillage method and solid finite element method,authors analyzed the transverse load distribution calculating methods for the fabricated hollow slab bridges.Also,authors analyzed the differences between the calculation results of transverse load distribution,explained the causes of error,discussed the accuracy and applicability of each calculation method,then proposed reasonable suggestions.The study results show that the transverse load distribution factor of side plate is decreased and unsafe,without considering the sectional geometrical properties’ differences between the side and medium plate;the calculation result of solid finite element method is accurate,compared with that,both of the hinge-jointed plate(girder) method and space grillage method are existing errors.更多还原
