discontinuous construction
Examples
- Researches on the deformation of the discontinuous interface of rock mass and the method of interface element stress
岩体不连续结构面变形研究与界面应力元法 - It is proved that the stability of rock mass high slope is mostly affected by lots of discontinuous structural faces like joints and faults , etc . it makes the rock mass be different from intact rocks completely in mechanical properties . so it is necessary for us to do some research on the deformation failure mechanism , and accordingly , we should do some research on the evolvement course and evaluation methods of stability about rock mass high slope
工程实践证明,节理岩体高边坡的稳定性取决于边坡中的不连续结构面,如节理、裂隙、软弱面和不同岩层的分界面,这类结构面的存在使岩体变形破坏的特性与完整岩石截然不同,因此,有必要加强对节理岩体高边坡变形破坏机制的研究及相应的节理岩体高边坡稳定性评价方法的研究。 - Referring to three kinds of plan irregularity , structures individually with four kinds of irregularity as eccentricity in one direction , eccentricities in two directions , re - entrant corner irregularity and diaphragm discontinuity have been analyzed to investigate the relationship between torsion effects and parameters of above irregular structures . the parameters and the schemes for determining the scope of structures with different kind of irregularity considering seismic action in two directions simultaneously are proposed , some conclusions have been get as following : it is indicated by the analysis results that torsion effect has no dependency relation with eccentric torsional angel adopted in code for seismic design for buildings . it is suggested that the eccentric torsional angel should not be take as the parameter of torsion effect of structures considering seismic action in two directions simultaneously ; for the structures with regular plan and elevation and with eccentricity in one direction due to irregular mass layout , the relative eccentricity can be take as the parameter of torsion effect of structures considering seismic action in two directions simultaneously ; for the structures with regular plan and elevation and with eccentricities in two directions due to irregular mass layout , the ratio of relative eccentricities in two directions and the angel of them can be take as the parameters of torsion effect of structures considering seismic action in two directions simultaneously ; it is indicated by the analysis results that the torsion effect has no dependency relation with re - entrant corner ratio adopted in code for seismic design for buildings as
所取得的主要结论有:结构的扭转效应与《抗震规范》所采用的扭转不规则指标即偏心扭转角之间的相关性较差,偏心扭转角不宜作为判断结构是否计及扭转效应及需考虑双向水平地震作用的界定指标;对于楼层间均匀偏心的多层单向偏心结构,建议采用相对偏心距作为需考虑双向水平地震作用的界定指标,并给出针对不同平面尺寸的界限相对偏心距;对于楼层间均匀偏心的多层双向偏心结构,建议采用两个主轴方向的相对偏心距及其夹角作为界定指标,结合单向偏心结构的界定方案进行需考虑双向水平地震作用的结构范围界定;凸凹不规则结构的扭转效应与凸凹比例无正相关关系, 《抗震规范》要求所有平面布置不对称的凸凹不规则结构计及扭转效应的规定欠妥当,建议凸凹不规则界限值从30改为15 ,只要求分析采用空间模型比较合适; 《抗震规范》关于有效楼板宽度较小的结构需计及扭转效应的规定很有必要,楼板局部不连续的结构需采用符合楼板实际刚度的计算模型予以分析,可使用相对偏心距(及其夹角)参照单向(和双向)偏心结构的界定方案,界定楼板局部不连续结构是否需要计入双向水平地震作用下的扭转效应。
