【摘要】：一体化计算机程序在建筑结构设计中的应用带来了利弊双重结果。有利方面是一体化计算程序将结构原理、规范要求、算法过程都隐藏于程序之中,使结构设计的门槛变低,设计效率大幅度提高,计算精度也更为精确;其不利方面正是因为计算程序的方便,结构原理概念的重要性被忽略,反而使得整体设计水平降低,结构优化意识不够强,只是一味地追求满足规范要求。对规范生搬硬套,对其中概念模糊,对结构简化计算模型不理解,缺乏手算能力,对程度计算结果没有更深入判断的能力,这些问题在设计人员中比比皆是,其根本原因是结构概念不清晰。本文要探讨的是概念设计优化方法在高层建筑结构设计中的应用,本文的主要工作包括:1、理论分析。分析高层建筑结构的设计特点及结构设计面临的挑战、结构优化的控制性指标及各指标之间的关系,阐述结构优化的基本理论、概念性简化估算方法。通过本阶段,主要目的是要树立结构概念优化的基本理论框架,并形成优化方法的指导性思路。2、案例分析。以某高层建筑为例,经过结构平面布置优化、结构构成及构件截面尺寸优化之后,可节省混凝土材料450m3(3.4%),可节省钢筋706.5吨(33.6%),大约节省材料费366万(25.3%)。本阶段主要目的是更具体地表达概念优化方法在工程中的应用,并印证其有效性。
[Abstract]:The application of integrated computer program in the design of building structure has brought about both advantages and disadvantages. The advantages are that the integrated calculation program hides the structural principle, specification requirements and algorithm process in the program, which makes the threshold of structural design lower, the design efficiency greatly improved, and the calculation accuracy more accurate. Because of the convenience of the calculation program, the importance of the concept of structure principle is ignored, which makes the overall design level lower and the consciousness of structural optimization not strong enough. These problems are common among designers, such as applying rigid rules, vague concepts, lack of understanding of simplified calculation models of structures, lack of manual computing ability, and lack of ability to judge the results of degree calculation in depth. The fundamental reason is that the concept of structure is not clear. This paper discusses the application of conceptual design optimization method in the structural design of high-rise buildings. The main work of this paper includes: 1, theoretical analysis. This paper analyzes the design characteristics of high-rise building structures and the challenges they face in structural design, the controlling indexes of structural optimization and the relationships among them, and expounds the basic theory of structural optimization and the conceptual simplified estimation method. Through this stage, the main purpose is to set up the basic theoretical framework of structural conceptual optimization, and form the guiding thinking of optimization method. Taking a high-rise building as an example, after the optimization of the layout of the structure, the structure composition and the section size of the members, the concrete material 450 m ~ 3 ~ (3) ~ 3 ~ (4) can be saved, the steel bar can be saved 706.5 tons ~ 33.6%, and the material cost is about 3.66 million ~ 25. 3%. The main purpose of this stage is to express more concretely the application of conceptual optimization method in engineering and to verify its validity.
