【摘要】：隨著土地資源的緊缺，人們逐漸將建筑發(fā)展到高空，近年來，超高層建筑的發(fā)展呈遍地開花的趨勢。超高層的發(fā)展伴隨著建筑功能更發(fā)達，結(jié)構(gòu)體系更加多樣化。隨著建筑層數(shù)的增加，水平荷載成為結(jié)構(gòu)設計的主要控制因素，結(jié)構(gòu)側(cè)移成為結(jié)構(gòu)設計的主要控制目標。在超高層建筑設計方案階段，結(jié)構(gòu)選型、概念設計，以及如何控制地震作用及風荷載作用下結(jié)構(gòu)的側(cè)向變形變得尤為重要。 超高層建筑不再是紐約、東京、香港或上海這樣人口密度超大土地資源超限的一線發(fā)達城市的專利，南昌也加入了超高層建筑發(fā)展迅速的城市之一，本文以南昌超高層框架—核心筒混合結(jié)構(gòu)寫字樓為背景做了以下研究： 南昌地區(qū)是典型的風荷載大，抗震設防烈度低的地區(qū)，本文以云中城項目為工程背景，用SATWE和Midas Building兩種軟件分別對該結(jié)構(gòu)進行了抗震設防烈度為6、7度規(guī)范法結(jié)構(gòu)計算，，以及抗震設防烈度為6、7度“安評法”結(jié)構(gòu)計算，首先驗證模型的準確性及適用性，然后對結(jié)構(gòu)的樓層剪力、樓層傾覆力矩、樓層位移以及樓層位移角進行對比，得出風荷載是對南昌地區(qū)超高層結(jié)構(gòu)的主要控制作用。說明在南昌地區(qū)，提高抗震構(gòu)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.
