【摘要】：为明确适停车辆的参数、荷载取值及设计方法,本文通过调研,统计了目前市场上500种轿车车型的长度、宽度、高度和重量,按照概率统计原理,确定车辆参数和荷载取值,并建议荷载的计算方法和组合方式；总结了立体车库的主要设计要求。通过大量的统计分析,给出了立体停车库相关设计参数的建议取值,建议车辆长度、宽度和高度取值分别为5000mm、1900mm和1850mm,以车辆尺寸为基础,按照规范规定的要求建议立体停车库单个停车位的长度、宽度和高度取值分别为6000mm、2400mm和2000mm；车辆荷载取2000kg；车库水平位移限值不宜超过层高的1/200。结合相关行业汽车规范和汽车库设计规范,对钢结构立体停车库的设计方法进行了总结归纳,针对车库各项参数的选取提出了设计要求。在确定了钢结构立体车库各项参数的情况下,选择一种综合性能较优的停车库——升降横移式立体停车库进行了分析。根据本文荷载统计及计算结果,建立了一种自行设计的升降横移式立体停车库钢结构骨架力学模型,对结构在不同工况和荷载作用下的受力性能进行了深入分析,得到了各工况荷载作用下结构的变形和应力状态。根据计算结果得出在最大偏载和对称满载工况下结构产生最大变形和最大应力,由此可对结构的强度、刚度及稳定性进行评价和对立体车库结构设计提出建议。
[Abstract]:In order to determine the parameters, load values and design methods of suitable parking vehicles, this paper counts the length, width, height and weight of 500 kinds of car models on the market, and determines the vehicle parameters and load values according to the principle of probability and statistics. The calculation method and combination mode of load are suggested, and the main design requirements of stereoscopic garage are summarized. Through a large number of statistics and analysis, the suggested values of the design parameters of the three-dimensional parking garage are given. The recommended values of the length, width and height of the vehicle are 5 000 mm / 1 900 mm and 1 850 mm respectively, which are based on the size of the vehicle. According to the specification, it is suggested that the length, width and height of a single parking space should be 6 000 mm / 2 400 mm and 2 000 mm respectively; the load of the vehicle should be 2 000 kg; and the limit value of the horizontal displacement of the garage should not exceed 1 / 200 of the floor height. The design methods of steel structure stereoscopic parking garage are summarized and summarized in combination with related industry automobile code and garage design code. The design requirements for the selection of garage parameters are put forward. Under the condition of determining the parameters of steel structure stereoscopic garage, a kind of parking depot with better comprehensive performance is selected and analyzed. According to the results of load statistics and calculation in this paper, a self-designed mechanical model of steel structure frame of elevating and transversely moving stereoscopic parking garage is established, and the mechanical behavior of the structure under different working conditions and loads is deeply analyzed. The deformation and stress states of the structure under various load conditions are obtained. According to the calculation results, the maximum deformation and maximum stress are obtained under the conditions of maximum eccentric load and symmetrical full load, thus the strength of the structure can be affected. Stiffness and stability are evaluated and suggestions for structural design of stereoscopic garage are put forward.
