【摘要】 本文以一个多跨多层大跨度预应力砼结构工程设计为例，提出了一种与现在常用结构方案不尽相同的解决大跨度结构设计的方案。尤其在解决总长度大的多跨大跨预应力连续梁的设计方面有所创新。这种结构方案构造合理，施工可行，经济效益显著。更多还原

【Abstract】 Taking the desigh of a multispan and multstory large span prestressed concrete frame structure as an example, this paper proposes a new structural scheme which is somewhat different fromthat commonly used 4n engineering practice for solving the designproblem of large span structures. It brings forth some new ideasespecially in the design of large and multiple span prestressedcone re ie continuous beams. The suggested scheme is rational andfeasibe in construction besides being pronounced on economicalbenefit.更多还原
