摘要
通过对8根缓粘结预应力简支梁的试验研究,分析了缓粘结预应力梁受力过程及破坏形态,运用现行规范关于有粘结以及无粘结预应力混凝土裂缝计算公式进行了裂缝计算,得出其裂缝开展与有粘结预应力梁非常接近。
Through the test of 8 pieces of stick-eased prestressing force simple support, it analyses the forcing course and breaking shape Of stick-eased prestressing force support. By using the actual formula of sticking and unsticking prestressing force eoncrete cracks, it concludes that its cracks is next to the sticking prestressing force support.
