发布时间：2019-04-17 18:18
【摘要】：随着土地资源的紧缺，人们逐渐将建筑发展到高空，近年来，超高层建筑的发展呈遍地开花的趋势。超高层的发展伴随着建筑功能更发达，结构体系更加多样化。随着建筑层数的增加，水平荷载成为结构设计的主要控制因素，结构侧移成为结构设计的主要控制目标。在超高层建筑设计方案阶段，结构选型、概念设计，以及如何控制地震作用及风荷载作用下结构的侧向变形变得尤为重要。 超高层建筑不再是纽约、东京、香港或上海这样人口密度超大土地资源超限的一线发达城市的专利，南昌也加入了超高层建筑发展迅速的城市之一，本文以南昌超高层框架—核心筒混合结构写字楼为背景做了以下研究： 南昌地区是典型的风荷载大，抗震设防烈度低的地区，本文以云中城项目为工程背景，用SATWE和Midas Building两种软件分别对该结构进行了抗震设防烈度为6、7度规范法结构计算，，以及抗震设防烈度为6、7度“安评法”结构计算，首先验证模型的准确性及适用性，然后对结构的楼层剪力、楼层倾覆力矩、楼层位移以及楼层位移角进行对比，得出风荷载是对南昌地区超高层结构的主要控制作用。说明在南昌地区，提高抗震构造措施比提高地震作用更加有效。
[Abstract]:With the shortage of land resources, people gradually develop high-rise buildings. In recent years, the development of super-high-rise buildings is showing a trend of blooming everywhere. With the development of super-high-rise, the function of building is more developed and the structure system is more diversified. With the increase of building floors, horizontal load becomes the main control factor of structural design, and the lateral displacement of structure becomes the main control target of structural design. In the design scheme stage of super-high-rise buildings, structural selection, conceptual design, and how to control the lateral deformation of structures under earthquake and wind loads have become particularly important. Super high-rise buildings are no longer the patents of first-tier developed cities such as New York, Tokyo, Hong Kong or Shanghai, where the density of super-dense land resources exceeds the limit. Nanchang has also joined one of the fast-growing cities of super-high-rise buildings. This paper takes Nanchang super-high-rise frame-core tube mixed office building as the background: Nanchang area is a typical area with large wind load and low seismic fortification intensity. This paper takes Yunzhong City project as the engineering background. Two kinds of software, SATWE and Midas Building, are used to calculate the seismic fortification intensity of the structure with the seismic fortification intensity of 6, the standard method of 7 degrees, and the seismic fortification intensity of 6 and 7 degrees "security evaluation method" respectively. The accuracy and applicability of the model are verified at first. Then by comparing the floor shear force, floor overturning moment, floor displacement and floor displacement angle, it is concluded that the wind load is the main control effect on the super-high-rise structure in Nanchang area. It shows that in Nanchang area, it is more effective to improve seismic structure than to improve seismic action.
