摘要
进行了8根高强混凝土梁的试验,其中6根为轻骨料混凝土梁,2根为普通混凝土梁。通过观察和量测,总结了高强轻骨料混凝土梁的性能,回归出有关参数的计算式。对梁的开裂弯矩、极限弯矩、刚度、挠度、裂缝宽度等的实测值与计算值进行了对比,为《轻骨料混凝土结构设计规程》的编制提供了参考依据。
The experiments of eight reinforced high strength concrete beams have been carried out. Six of which are made of light weight aggregate concrete（LWAC）and others are made of normal density concrete（NDC）. On the basis of observation and meansuring, the performance of high strength LWAC beams is concluded, and some useful data and formula in design are given. Using different formula, cracking moment, ultimate moment, section stiffness, deflection and width of crack etc. are calculated, and the results are compared with the data in experiments. It can be used as reference and evidence for editors of the Design Code of High Strength and Light Weight Aggregate Concrete Strature.
