摘　　要：结合与哈尔滨工业大学合作进行的科研项目"火力发电厂主厂房钢结构抗震设计方法的研究与应用"和实际工程的设计,解决了"支撑框架"这种新的结构体系在设计中所遇到的许多问题.本文作为设计体验的系列文章之三,简要介绍对于火力发电厂主厂房这样的平面、竖向和质量不规则的结构,在结构布置时所遇到的困难;讨论为使结构具备必要的抗震承载力,在结构布置时应遵守的原则;对如何合理设置垂直支撑、水平支撑和有人字形支撑的梁的侧向支承等关键问题,提出了意见和建议.Under the guidance of the research project 'Research and Application of Seismic Design Method of Structural Steel Main Building in Fire Power-generating Station' carried out by our institute in cooperation with the Harbin Institute of Technology,and the guidance of design of specific projects,many problems encountered in designing 'braced frames' structure system are solved.This paper is the third part of a series of articles of the design experience.The structure system of main power building which has such an irregular shape and weight,and the difficulties encountered in the structural arrangement are introduced briefly.The principle of structural arrangement is discussed in order to make that the structure has necessary aseismic capacity.Some comments and suggestions of reasonable arrangement for vertical bracing,horizontal bracing,lateral support of girder intersected by chevron bracing,are proposed.
