在多跨檩条设计中,一般假设梁是连续的,以避免进行节点分析。当采用等强度和刚性连接时,该假设是合理的。常用的两种连接类型为:搭接连接和套管连接。套管连接的优点主要是在装配过程中节约了时间和费用。而对于大部分Z型截面,采用搭接连接方式时,可以准确地计算出搭接部分的长宽比。对部分加劲的Z型套管连接节点进行试验和数值分析,研究它们的结构性能和确定合理的刚度和强度。 In multi-span designs, it is generally assumed that beams are continuous to avoid node analysis. This assumption is reasonable when using equal strength and rigid connections. The two common connection types are: Lap and Sleeve connections. The advantages of casing connections are mainly savings in time and money in the assembly process. For most Z-section, lap connection method, you can accurately calculate the lap part of the aspect ratio. Experimental and numerical analyzes were conducted on partially stiffened Z-type casing joints to study their structural behavior and to determine reasonable stiffness and strength.
