无粘结预应力混凝土结构裂缝控制及验算建议

本文首先通过大量的调查研究提出了无粘结预应力混凝土结构裂缝控制建议；然后，以已有研究成果为基础，通过计算机模拟分析，建立了用名义拉应力控制ＢＵＰＣ结构裂缝宽度的简化方法，最后给出了ＢＵＰＣ结构裂缝验算建议。

A Recommendation of Cracking -control and Checking Calculation in Bond-Unstable Prestressed Concrete Structures

In the first place, this thesis provides the recommendation of cracking-control and checking calculation in BUPC (bond-unstable prestressed concrete) structures through a lot of research. Secondly, on the basis of research results, through calculation analysis, creates a simplified method of the width control of cracking in BUPC structures by nominal tensile stress and provides the recommendation of cracking -control and checking calculation in BUPC structures.
