摘要
围绕大跨度预应力混凝土转换梁工程,建立了空间计算模型,优化了结构平面布置,着力讨论了楼板、结构自重、预应力张拉施工方案等因素对预应力转换梁抗裂验算的影响,以及预应力在复杂结构中对周边构件受力的改变,提出了在设计中应注意的问题及相应措施。
Focus on project of long span prestressed concrete transfer beam, the spatial calculated models are built. The structural plan arrangement is optimized. Some factors such as floor members, self-weight of structure, construction process of prestressing having influence upon cracking capacity are discussed. Mechanics of periphery members are changed according with prestressing in sophisticated structure. The design method is put forward to satisfy the technical specification.
