cornering ratio中文什么意思
例句與用法
- 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
所取得的主要結(jié)論有：結(jié)構(gòu)的扭轉(zhuǎn)效應(yīng)與《抗震規(guī)范》所采用的扭轉(zhuǎn)不規(guī)則指標(biāo)即偏心扭轉(zhuǎn)角之間的相關(guān)性較差，偏心扭轉(zhuǎn)角不宜作為判斷結(jié)構(gòu)是否計(jì)及扭轉(zhuǎn)效應(yīng)及需考慮雙向水平地震作用的界定指標(biāo)；對(duì)于樓層間均勻偏心的多層單向偏心結(jié)構(gòu)，建議采用相對(duì)偏心距作為需考慮雙向水平地震作用的界定指標(biāo)，并給出針對(duì)不同平面尺寸的界限相對(duì)偏心距；對(duì)于樓層間均勻偏心的多層雙向偏心結(jié)構(gòu)，建議采用兩個(gè)主軸方向的相對(duì)偏心距及其夾角作為界定指標(biāo)，結(jié)合單向偏心結(jié)構(gòu)的界定方案進(jìn)行需考慮雙向水平地震作用的結(jié)構(gòu)范圍界定；凸凹不規(guī)則結(jié)構(gòu)的扭轉(zhuǎn)效應(yīng)與凸凹比例無正相關(guān)關(guān)系， 《抗震規(guī)范》要求所有平面布置不對(duì)稱的凸凹不規(guī)則結(jié)構(gòu)計(jì)及扭轉(zhuǎn)效應(yīng)的規(guī)定欠妥當(dāng)，建議凸凹不規(guī)則界限值從30改為15 ，只要求分析采用空間模型比較合適； 《抗震規(guī)范》關(guān)于有效樓板寬度較小的結(jié)構(gòu)需計(jì)及扭轉(zhuǎn)效應(yīng)的規(guī)定很有必要，樓板局部不連續(xù)的結(jié)構(gòu)需采用符合樓板實(shí)際剛度的計(jì)算模型予以分析，可使用相對(duì)偏心距（及其夾角）參照單向（和雙向）偏心結(jié)構(gòu)的界定方案，界定樓板局部不連續(xù)結(jié)構(gòu)是否需要計(jì)入雙向水平地震作用下的扭轉(zhuǎn)效應(yīng)。
