- ( 3 ) the countermeasures and ways of the reconstructing and extending steel complex are proposed from the aspects of technique and equipment , general layout system , transportation , vertical design , pipe network , afforestation and beautification , general layout management and so on
( 3 )从工艺设备、总平面布置系统、运输、竖向设计、管线综合、绿化美化、总图管理等方面提出钢铁企业改扩建的对策及途径。 - In addition , effects of several factors such as local site conditions , focal mechanism , epicentral distance and seismic magnitude on these parameters are discussed , and several significative results and conclusions are obtained . in all records there are about 1 / 3 vertical ground motion ’ s peak acceleration bigger than 2 / 3 of the corresponding horizontal one , so the action of vertical ground motion should not to be underestimated . vertical design response spectrum equals that the horizontal design response spectra times 65 % is probably unsafe when period is short , and suggest adopting different coefficients when at different periods
本文基于对大量欧洲强震记录的研究,分析了地震动竖向与水平向分量在峰值加速度、反应谱值、频谱周期等参数方面的差异,以及这些参数与场地、震源机制、震级和震中距的关系,得到了以下有意义的结果和结论:在本文分析的地震记录中大约1 / 3的记录加速度峰值比大于2 / 3 ,竖向地震动分量的作用不可低估;在短周期,竖向地震动影响系数的最大值仅取为水平向地震动影响系数最大值的65 %是偏于不安全的,可以考虑按周期分段采用不同的折减系数;我国现行抗震规范中设计反应谱特征周期的取值偏低,可能是偏于不安全的;竖向与水平向地震动分量卓越周期的比值在0 . 7 - 0 . 9之间,竖向设计反应谱的特征周期应有单独规定。
