The result by MIDAS software shows that the influence of dimensions of earthquake wave including unidirectional earthquake wave and bidirectional earthquake waves and damping ratio could be affected greatly when analyzing the elastic time history for the frequent earthquake,and when analyzing the elastic-plastic time history for the unusual earthquake.
利用MIDAS软件对结构进行多遇地震作用下的弹性时程分析和罕遇地震作用下的弹塑性时程分析,表明地震波输入维数(单向地震波和双向地震波)、阻尼比对结构的抗震性能有较大影响,并根据分析结果提出了相应的建议。
2) bi-directional horizontal seismic action
双向地震
1.
In the codes for anti-seismic design of buildings in countries with frequent earthquakes, the moment amplification factor of columns is generally prescribed to apply within two orthogonal plane frames that intersect at the column, except that the New Zealand Concrete Structures Standard NZS3101 considers the effect of bi-directional horizontal seismic action on the moment amplification factor.
在世界各主要多地震国家的建筑抗震设计规范中,普遍采用的柱端弯矩增强措施一般在与柱正交的两个主轴方向上的各平面框架内施行,仅新西兰NZS3101规范采用简化方法考虑了双向地震作用对柱端弯矩增大系数的影响。

6) bilateral seismic response
双向地震反应
1.
The bilateral coupled friction force of sliding-friction bearings is simulated and the comparing analysis on unilateral and bilateral seismic response of sliding base-isolated structure is carried out by the program of dynamic analysis on base-isolated structures (DABIS).
通过对滑移摩擦支座摩擦力双向耦合性能的模拟,采用基础隔震结构动力分析程序DABIS对基础滑移隔震结构进行了单向和双向地震反应对比分析,分析表明在双向地震作用下结构各层的加速度反应较小,隔震层的层间位移较大,而上部结构的层间位移较小,并且在双向地震作用下,支座的最大位移明显大于单向地震作用时的支座最大位移,因而在确定支座最大位移时应考虑双向地震作用的影响。

高低分分段双向截除法
即在考核打分时为消除考核者主观打人情分的影响,而对考核得出的结果按所有考核成员得出分值的平均值的一定比例限定高低分区间,对超过此区间的考核分数的使用进行限定,在统计成绩时而不予考虑、计算。此种方法可控制打分者在一定程度上约束自己的打分行为,将其控制在一定程度内,否则其打出的分数将视为无效,实际上也即相当于放弃了自己的投票权。由于实际考核工作中,评委主观打分和打人情分的倾向较普遍,因而对于优化考核有一定意义。但此种方法对考核者人数较多的情况下更适用,而考核者人数较少时(更易受事前操纵、考核者信息泄露风险系数增加、恶意评分者博弈动机增强等因素影响),其有效性将会降低。
