【摘要】：地震災害一直是困擾人類社會的最主要的自然災害之一。尤其進入21世紀以來,地震災害頻發(fā),給人類社會造成了不可估量的損失。而高層住宅結(jié)構在地震活動當中損壞尤其嚴重,造成的傷亡在各類建筑中也是最大的。另一方面,結(jié)構設計人員往往由于結(jié)構選型的不合理而造成各種不必要的浪費。鑒于此,本文將就不同抗震烈度的高層住宅結(jié)構進行結(jié)構選型及經(jīng)濟性的分析,以期在符合安全性的條件下達到最節(jié)省的效果。本文具體工作包括以下幾個方面:一、結(jié)構選型及方案布置階段。通過資料收集,依據(jù)現(xiàn)行規(guī)范,初步確定高層住宅所能采用的結(jié)構類型及其特點,分析其結(jié)構計算、構造等相關問題;根據(jù)抗震規(guī)范等相關規(guī)范要求,結(jié)合實例和上述初選結(jié)果,分別確定在抗震烈度為6度、7度、8度時所能采用的結(jié)構類型;就上述選取的每一種結(jié)構類型進一步選擇兩種布置方案。二、結(jié)構計算階段。根據(jù)上述選型結(jié)果,針對同一高層住宅工程,在抗震烈度為6度下建立結(jié)構的整體模型。依據(jù)相關規(guī)范對其進行計算,分析相關參數(shù)的選取。采用相同方法分別進行7度、8度的結(jié)構分析。三、分析比較階段。根據(jù)上述計算結(jié)果,通過對控制性參數(shù)、經(jīng)濟性指標的比較,分別選取抗震烈度為6度、7度和8度時的最優(yōu)布置方案。四、不同抗震烈度下的比較。對于上述計算結(jié)果,比較三種抗震烈度下的三種最優(yōu)方案,進而分析不同抗震烈度地區(qū)高層住宅結(jié)構的選型特點,以供設計人員進行結(jié)構設計時參考。
[Abstract]:Earthquake disaster has been one of the most important natural disasters in human society. Especially since the 21 st century, frequent earthquake disasters have caused incalculable losses to human society. The damage of high-rise residential structures is especially serious in seismic activities, resulting in the largest casualties in all kinds of buildings. On the other hand, structural designers often cause a variety of unnecessary waste due to unreasonable structural selection. In view of this, the structural selection and economic analysis of high-rise residential structures with different seismic intensity will be carried out in order to achieve the most economical effect under the condition of safety. The specific work of this paper includes the following aspects: first, structure selection and layout stage. Through the data collection, according to the current code, the paper preliminarily determines the structural types and characteristics of high-rise residential buildings, and analyzes the structural calculation, construction and other related problems. According to the requirements of seismic code and other related codes, combined with the examples and the results of the primary selection, the structural types can be adopted when the seismic intensity is 6 degrees, 7 degrees and 8 degrees respectively. Two layout schemes are further selected for each of the structural types selected above. Second, structure calculation stage. According to the above selection results, the whole model of the structure is established under the seismic intensity of 6 degree for the same high-rise residential project. It is calculated according to the relevant specifications, and the selection of relevant parameters is analyzed. The same method was used to analyze the structure of 7 degrees and 8 degrees respectively. Third, analysis and comparison stage. According to the above calculation results, the optimal arrangement scheme is selected when the seismic intensity is 6 degrees, 7 degrees and 8 degrees, respectively, by comparing the control parameters and economic indexes. Fourth, the comparison of different seismic intensity. For the above calculation results, the three optimal schemes under three kinds of seismic intensity are compared, and then the selection characteristics of high-rise residential structures in different seismic intensity areas are analyzed, which can be used as a reference for designers in structural design.
