JPKIC 2、features 结构设计原黑 1,safety factor K>1,a lager k will have a higher safety and more material. 2.Without consideration of diversity of function 1 )load-carrying capacity. 2)service performance,crack and deformation. 3,The determination of safety is by experience judgment and no scientific basis. 3,applicable condition Non-line-shape structures,such dam,spatial shell structures. No equations in code.So elastic mechanism method is a useful tool 2、features 1、safety factor K >1, a lager k will have a higher safety and more material. 2、Without consideration of diversity of function 1）load-carrying capacity. 2) service performance, crack and deformation . 3、The determination of safety is by experience judgment and no scientific basis. 3、applicable condition Non-line-shape structures, such dam, spatial shell structures.
