摘要:
用精确解析方法研究穿斗木结构的承载能力,将杆件之间的相互作用力看做是施加于杆件上的未知外力,采用迪拉克函数和偶极函数描述集中力和集中弯矩,从而得到各杆件受力和变形的解析解。由构件的边界条件以及杆件连接处位移和转角的协调条件确定未知参数,用最大剪力、最大轴力、最大弯矩和稳定性来校验各杆件的承载能力,以最少用材为目标函数,对穿斗木结构各杆件的截面尺寸进行优化设计,最后给出应用实例,并提供了具有实际应用价值的最优设计参数表。
Abstract:
An exact analytical method was used to study the bearing capacity of through-jointed timber frames,in which the interaction forces among members were considered as unknown external forces.The dirac function and the doublet function were used to describe the concentrated forces and concentrated moments,and then the analytical solutions of forces and deformations of each member were obtained.Unknown parameters were determined by the boundary conditions of members,and the displacements and rotations consistent conditions at junctions,while the bearing capacities of members were verified according to their maximum of shear force,axial force,moment and stability.Finally, a practical example was given,in which the minimum wood usage was the objective function in optimal design when calculating the section size of through-jointed timber frame members, and optimal design parameters for practical application were provided.
