【摘要】：随着我国经济的快速发展,私家车数量的不断增加,造成大中城市的交通堵塞。虽然现在有一些控制车辆增长的措施,但车辆依然在增长。车辆的不断增加对车位的需求也随之增加。但由于城市中土地资源的紧缺,无法提供更多的停车位置,形成了城市中土地资源需求矛盾,形成停车难的问题。需要寻求一种提高单位面积上停车数量的办法成为解决问题的关键。本文通过对比分析不同类型的立体车库之间的优缺点,综合考虑各种立体车库的优点及自身的特性,设计了一种垂向循环横向平移的立体车库,可有效缩短立体车库的存取车辆的时间,提高单位面积上的存车数量,便捷实现取车的过程。随后通过使用ANSYS的APDL语言建立垂向循环横向平移立体车库的有限元模型,其中用到了梁单元、面单元和质量单元。对空载、半载和全载条件下的立体车库进行模态分析,得出前二十阶频率和相对应的振型,并进行对比分析,得到立体车库在不同状态条件下的敏感频率。为了保证立体车库的结构可靠性,根据国标中《建筑结构载荷标准》中的规定对立体车库进行风载荷作用下的稳定性分析。在立体车库不同高度下,根据不同的风速与建筑物表面的基本风压关系,同时综合考虑到风载荷施加标准值与特定高度处的风振系数、风载荷体型系数、风压高度变化系数及基本风压之间的关系,可以考虑到不同风级条件下的建筑表面风压施加方法。同时根据《建筑结构抗震规范》的规定,通过对设计的立体车库进行抗震性能的分析,使用《建筑结构抗震规范》中的规定对立体车库进行评价。进行抗震计算时使用时程分析法和地震谱分析法,在计算过程中读入振动加速度较大的EL—CENTRO波,较好的保证了结构的安全性。
[Abstract]:With the rapid development of our economy and the increasing number of private cars , the traffic jam of large and medium - sized cities is caused . Although there are some measures to control the growth of the vehicles , the vehicle is still growing . However , because of the shortage of land resources in the city , it is impossible to provide more parking positions , thus forming the problem of the contradiction of land resource demand in the city and forming the parking space . It is necessary to seek a way to improve the number of parking lots on the unit area and become the key to solve the problem . This paper analyzes the advantages and disadvantages of three - dimensional garage by comparing the advantages and disadvantages of three - dimensional garage , designs a three - dimensional garage with vertical circulation and horizontal translation , and designs a finite element model of vertical circular cross - translation stereoscopic garage by using ANSYS APDL language . In order to guarantee the structural reliability of the three - dimensional garage , the stability of the three - dimensional garage under wind load is analyzed in accordance with the provisions of the national standard . At different heights of the three - dimensional garage , the relationship between the standard value of the wind load and the wind - vibration coefficient , the wind load type coefficient , the height variation coefficient of the wind pressure and the basic wind pressure are comprehensively considered in consideration of the relationship between the standard value of the wind load and the wind - vibration coefficient , the wind load type coefficient , the wind pressure height variation coefficient and the basic wind pressure , and the method for applying the wind pressure to the building surface under different wind - level conditions can be taken into account . At the same time , according to the stipulation of the earthquake - proof specification of the structural building structure , the three - dimensional garage is evaluated by the analysis of the seismic performance of the designed three - dimensional garage . When the seismic calculation is carried out , the time - history analysis method and the seismic analysis method are used to read the EL - CENP wave with larger vibration acceleration during the calculation process , and the safety of the structure is guaranteed better .
