【摘要】 通过给定某些特定假设条件,利用反应谱原理计算出不同场地类型、设防烈度、自振周期和阻尼比情况下的地震力,利用这些计算结果来分析判断各因素与地震力之间的作用关系,计算结果表明:利用抗震设计反应谱计算出的地震力,当诸多因素中只有唯一变量时,其与自振周期成反比,与阻尼比成反比,与设防烈度成正比,与场地类型成正比。更多还原

【Abstract】 Through given certain assumptions,seismic forces are calculated for different site categories,seismic fortification intensity,natural period and damp ratio by the seismic design response spectra,the use of these calculation results is to analyze and judge the role of relationships between various factors and seismic force.The results show that when there is the only one variable in a number of factors,seismic force,which is calculated by the seismic design response spectra,is inversely proportional to the natural period and damp ratio,and is proportional to seismic fortification intensity and site categories.更多还原
