Safety in Design
The concept of safety in the context of current design is complex .The danger or risks inherent in structural design arise from the designer's limited knowledge of the exact environment in which the structure may have to operate and also of the material properties and performance of the Structure itself.In the context of building design and construction ,safety is sought by using the best design and construction techniques available ,the best materials and construction expertise and the best environmental data.With the design calculations,margins are ensured more specifically by the use of appropriate numerical factors .for the
purpose of this discussion ,it is accepted that all practical controls on material properties ,workmanship,details ,and so forth,are exactly as specified by the designer.Such an assumption is necessary to establish any analytical process of design in which formal control over safety are incorporated.
Consider the limit state or the Load and Resistance Factor Design approach to design.These methods appear to place equal importance on meeting serviceability requirements as on meeting those for ultimate limit states.It is arguable ,however,that the principal objective of design is to produce serviceable structures and further ,that completed structures complying with serviceability requirements are ipso-facto safe.The question arises therefore :what function does the establishment of ultimate limit states perform visa- vi the security of structures It can be said that the requirement of stability under extreme load states provide a specific security margin over the serviceability condition for the explicitly considered load cases.The evaluation of margin does not ,within the conventional meaning of such a factor ,result in a partial safety factor.Indeed,this part of the safety control mechanism is more akin to design requirement in that it affects primarily the nature of structural behavior.

在目前的设计中的安全概念是复杂的,危险或在结构设计中所固有的风险,从有限的确切环境设计师的知识结构可能有操作和材料的性能和结构性能出现.在建筑设计和施工安全要求使用最好的设计和施工技术,最好的材料和施工的专业知识和最好的环境数据与设计计算保证金,确保使用适当的数值更具体因素.这次讨论的目的,它是接受所有
实际控制材料的性能做工的细节等等都严格按照指定的设计师这样的假设是必要建立任何分析
考虑极限状态或负荷和阻力系数设计方法来设计,这些方法出现会议可维护性的要求放在同等的重要性,在满足极限状态,这是值得商榷的,但是,这种设计的主要目标是生产维修结构进一步,完成结构符合适用性要求是IPSO的事实safe.the问题出现
因此,什么样的功能建立极限状态进行面对面的安全结构?可以说,在极端负载状态下的稳定性要求提供了明确考虑负载情况下的适用性条件,特定的安全保证金评价的保证金在不确实这部分的安全控制机制的设计要求,它主要影响更像是在一个局部安全系数等因素导致传统意义结构的性质.
