论文简介:

Structure in the long-term natural environment and under the use environment's function, its function is weaken inevitably gradually, our structural engineering's duty not just must finish the building earlier period the project work, but must be able the science appraisal structure damage objective law and the degree, and adopts the effective method guarantee structure the security use, that the structure reinforcement will become an important work. What may foresee will be the 21st century, the human building also by the concrete structure, the steel structure, the bricking-up structure and so on primarily, the present stage I will think us in the structure reinforcement this aspect research should also take this as the main breakthrough direction.

转换层混凝土标号的问题

对框架结构的混凝土标号一直比较茫然。比如局部带转换的高层,转换梁的标高是C40,主楼和裙房所有楼板和梁都要用C40吗?转换层以下的各层柱子可以变标号吗,比如从C50~C45?裙房柱子可以不用这么高,比如C30行吗?还有这样抠标号省下的造价比起结构安全和施工来说到底划不划算?
