摘要
本文通过对四边简支的双向板的分析,阐述了长宽比不同的板在不同荷载、不同配筋方式下的稳定问题、有限预应力板在拉应力控制时所需的预压力、以及临界荷载与有限预压力的相互关系等,推导出了临界荷载Pcr、有限预压力Ny的相应公式,为工程应用提供了依据。
This artide elaborates some problems about the plate stability prestressed pressure demanded in some stress state, and the relations between these two questions by analysing various sizes of two-way concrete slab shich are simply supported on all sides, when they are subjected to various types of loading and reinforcement patterns. Meanwhile, some formulas on critical load P cr and prestress N y are derived.
