【摘要】： 大跨空間網(wǎng)殼結(jié)構(gòu)因其造型優(yōu)美,受力合理,結(jié)構(gòu)靈活多樣,機(jī)械化、工廠化程度高等特點(diǎn),已經(jīng)成為近年來發(fā)展較快的一種空間結(jié)構(gòu),在體育館、會展中心、游泳池、餐廳、工業(yè)廠房等建筑中獲得廣泛應(yīng)用。 網(wǎng)殼結(jié)構(gòu)的跨度越來越大,隨著跨度的加大引起屋蓋自重的增加,在曲面網(wǎng)殼結(jié)構(gòu)設(shè)計(jì)中遇到的最大問題是大跨空間網(wǎng)殼結(jié)構(gòu)具有很大的水平推力,下部結(jié)構(gòu)往往難以承受。而且我國大部分地區(qū)處于地震區(qū),需要考慮地震的影響,為此“如何減小大跨空間網(wǎng)殼結(jié)構(gòu)地震反應(yīng)”的問題顯得尤為突出。近年來,隨著高層建筑結(jié)構(gòu)減震控制技術(shù)研究的深入,人們已經(jīng)將這門技術(shù)應(yīng)用到大跨空間網(wǎng)殼結(jié)構(gòu)上,通常采用板式橡膠支座來解決以上問題。因此,對橡膠支座的水平剛度和抗震性能進(jìn)行深入細(xì)致的研究有著非常重要的理論意義和工程實(shí)用價(jià)值。 本文主要進(jìn)行了以下工作： 1.’對工程中經(jīng)常使用的板式橡膠支座,通過改變螺栓直徑及個數(shù)、橡膠墊板的厚度和平面尺寸、螺栓非對稱布置時的加載方向,對橡膠支座的水平剛度進(jìn)行了分析。 2.利用ANSYS大型通用有限元分析軟件對帶螺栓板式橡膠支座的滯回性能進(jìn)行了分析,并與普通橡膠支座、鉛芯橡膠支座的滯回性能做了簡單對比。 3.最后由帶螺栓板式橡膠支座的滯回曲線得出其骨架曲線,并做了簡單分析。 結(jié)果表明：螺栓可以有效改善板式橡膠支座的水平剛度和滯回性能,使其滯回曲線較飽滿,表現(xiàn)出較好的滯回性能和耗能能力。同時通過螺栓非對稱布置時,不同加載方向?qū)Π迨较鹉z支座水平剛度的影響總結(jié)了螺栓的布置原則,為板式橡膠支座的設(shè)計(jì)提供可借鑒的依據(jù)。本文的研究內(nèi)容及成果對板式橡膠支座在實(shí)際工程中的應(yīng)用推廣具有一定的理論和現(xiàn)實(shí)意義。
[Abstract]:Because of its beautiful shape, reasonable force, flexible structure, mechanization and high degree of factory, the large-span space reticulated shell structure has developed rapidly in recent years, in gymnasium, exhibition center, swimming pool, restaurant, etc.Industrial buildings and other buildings have been widely used.The span of latticed shell structure is getting larger and larger. With the increase of span, the weight of roof increases. The biggest problem encountered in the design of curved reticulated shell structure is the large horizontal thrust of long-span space latticed shell structure, which is often difficult to bear in the lower part of the structure.In addition, most areas in China are in the earthquake area, so the problem of "how to reduce the seismic response of large space reticulated shell structure" is especially prominent.In recent years, with the development of the research on shock absorption and control technology of high-rise building structure, people have applied this technology to the large-span space latticed shell structure, usually using the plate rubber bearing to solve the above problem.Therefore, it is of great theoretical significance and practical value to study the horizontal stiffness and seismic performance of rubber bearings.The main work of this paper is as follows:1'The horizontal stiffness of rubber bearing is analyzed by changing the diameter and number of bolts, the thickness and plane size of rubber pad, and the loading direction when bolts are unsymmetrical arranged.2.The hysteretic properties of rubber bearings with bolts and plates were analyzed by using ANSYS software, and the hysteretic properties of rubber bearings with bolts and lead rubber bearings were simply compared with those of common rubber bearings and lead rubber bearings.3.Finally, the skeleton curve is obtained from the hysteretic curve of the rubber bearing with bolt and plate, and a simple analysis is made.The results show that the bolt can effectively improve the horizontal stiffness and hysteretic performance of the plate rubber bearing, make the hysteretic curve fuller, and show better hysteretic performance and energy dissipation ability.At the same time, through the influence of different loading direction on horizontal stiffness of plate rubber bearing, the principle of bolt arrangement is summarized, which can be used as a reference for the design of plate rubber bearing.The research contents and results of this paper have certain theoretical and practical significance for the application and popularization of plate rubber bearings in practical engineering.
