耗能支撑框架结构中耗能支撑数量的估算
|
摘要
提出耗能支撑数量的估算公式,并通过模型计算确定了耗能支撑数量影响系数β在8度Ⅲ类场地,9度Ⅰ类场地下的取值,以及影响β的因素。提出了利用周期估算耗能支撑数量的计算公式,简化了设计流程,修正了以往的计算公式。
Two formulas about estimating the amount of friction energy dissipation braces are proposed in this paper.The influence coefficient β under the third location of 8° and the fist location of 9° area is fixed by calculating models.Factors that influenced β are also pointed out.The formula used before is modified.
