七、分项系数的确定 从设计表达式可知,分项系数包括:重要性系数、荷载系数和抗力系数。重要性系数的取值已作了交待,不再重述。荷载系数是由《建筑结构设计统一标准》统一确定的,本文仅简单介绍其确定的原则与具体的系数取值,而重点讨论如何确定木结构构件抗力系数。 (一)荷载系数 荷载系数Y_G、Y_Q是以永久荷载与一种可变 Seven, the determination of the sub-component coefficient From the design expression, the sub-factor includes: importance coefficient, load factor and resistance coefficient. The value of the importance coefficient has been confessed and will not be repeated. The load coefficient is uniformly determined by the “Unified Standard of Building Structure Design”. This article only briefly introduces the principle and the specific value of the determined coefficient, but focuses on how to determine the resistance coefficient of the wooden structural member. (I) Load factors Load factors Y_G, Y_Q are permanent loads and variable
