四川省建筑科学研究院承担的“无粘结预应力混凝土结构的应用与综合技术研究”课题已通过技术鉴定.该研究成果解决了关于刚度较大的剪力墙或剪力筒之间的板能否建立预应力的问题.在国内首次设计并通过试验,证实了在简体四角处取消扁梁的可行性,不仅使建筑物造形美观,施工方便,且能节约投资;对无粘结预应力混凝土设计中的内力 The project of “Research on the Application and Comprehensive Technology of Non-bonded Prestressed Concrete Structures” assumed by the Sichuan Academy of Building Research has passed the technical appraisal. The research results have solved the problem of the plates between the shear walls or shear cylinders with high rigidity. Whether the problem of prestressing can be established. The first time in the country to design and pass the test, the feasibility of canceling the flat beam at the four corners of simplified Chinese is confirmed. It not only makes the building shape beautiful, the construction is convenient, but also can save the investment; the unbonded prestress Internal force in concrete design
