工程建筑物要讲安全。但安全不能绝对化,只能在总费用和安全要求之间折衷求解。换言之,要在一定的安全程度要求下,做到总费用最低。工程设计的基本要求就在于此。总费用包括三个部分:造价、维修费、以及一旦坍塌势必支付的有关费用。 研究安全,实际上是研究损坏规律。现代规范衡量工程建筑物的安全,主要看两个 Engineering buildings to talk about safety. But safety can not be absolute, it can only be compromised between the total cost and safety requirements. In other words, to a certain degree of safety requirements, to achieve the lowest total cost. This is the basic requirement of engineering design. The total cost consists of three parts: the cost, maintenance costs, and the costs that must be paid in the event of a collapse. Studying safety is actually studying the law of damage. Modern norms to measure the safety of engineering buildings, mainly to see two
