摘要
本文讨论两个问题:1.抗震重点设防类的工程,电算时是否必须填写γ0=1.1?若填写γ0=1.0将存在什么隐患?2.PHC管桩桩身受压承载力该怎么算?要不要全额扣除混凝土有效预应力?这两个问题都是工程设计中很现实的问题,业内也有不同看法。本文所述个人见解仅供讨论参考。
In this paper two problems are discussed ： 1. In structure calculation of the important classification of seismic protection, does the structure important coefficient T0 must be used as 1.19 Are there any hidden troubles if To is used as 1.0.9 2. How to calculate the bearing capacity of anti - pressing of PHC pipe pile.＇？ Should it deduct the total effective prestress of concrete.＇？ The two problems are practical in building designing, and the engineers have different opinions. The personal view in this paper is just taken out to be discussed and referenced.
