拉—压预应力混凝土结构优化配筋设计

Optimum design of tension—compression prestressed concrete structures

给出调质结构钢预压控制应力的取值,建立结构构件承载力公式,给出受拉预应力筋用量Ap、预压调质钢管用量AT、受拉非预应力纵筋用量As及受压非预应力纵筋用量As′的优化关系。实际工程算例说明拉—压预应力混凝土结构具有一定的优越性。

This paper offers numerical value of adjusting-quality steel pre-compression control stress, establishment of structures bearing power equation , and offers the optimum connection on value of tendons area （Ap）, value of pre-compression component area （AT）, value of common reinforcement in concrete tension-section （As）, and value of common reinforcement in concrete tension-section（As＇ ）. Moreover, examples of engineering explain advantage of tension - compression prestressed concrete structures.
