Study on the effect of the circulate loading on the young ' s model of rock in a low stress state 低應(yīng)力水平下循環(huán)載荷對(duì)巖石楊氏模量影響的研究
A coefficient of 0 . 9 can be multiplied to ensure the safety of structures . by and large , the back covered porous brick wall with constructional column and gird beam has the same shearing strength under low circulated load as other porous brick wall , so the shear resistance and aseismatic capability can be calculated by the standard method . the experiment indicates that the back covered porous brick wall has good energy absorbing as well as deforming capability , and it can satisfy the requirement of aseismatic structures 盲孔多孔磚砌體的通縫抗剪強(qiáng)度略低于規(guī)范計(jì)算值,為保證結(jié)構(gòu)安全,建議設(shè)計(jì)時(shí)乘以系數(shù)0 . 9 ;盲孔多孔磚墻片在低周反復(fù)荷載作用下抗剪承載力與其它多孔磚墻片基本相當(dāng),可按規(guī)范方法計(jì)算其抗震抗剪承載力;試驗(yàn)證明帶構(gòu)造柱及圈梁的盲孔多孔磚墻片有較好的吸能、變形能力,可以滿足抗震結(jié)構(gòu)的要求。
In the static nonlinear pushover analysis , basic concepts and different applicable methods of the static nonlinear pushover analysis are summarized . then the lateral load pattern and the target displacement , which are key problems of the static nonlinear pushover analysis , are improved . the new developed lateral load pattern is the instantaneous adaptive lateral load pattern gained by the internal force of the structure , and the new developed capacity spectrum method combined with the code response spectrum is used to gain the target displacement . at the same time , a pushover analysis of circulating load pattern is developed , and a relevant static nonlinear pushover analytic program is provided . the analytic results of two examples demonstrated that the instantaneous adaptive lateral load pattern is able to reasonably capture the important response attribute and that the pushover analysis of circulating load pattern compared with the pushover analysis of single direction load pattern can more accurately reflect the effect of the earthquake 在非線性靜力分析( pushover分析)中,綜合闡述了pushover分析的理論基礎(chǔ)和不同的具體應(yīng)用方法,并在pushover方法的關(guān)鍵問(wèn)題荷載分布模式和目標(biāo)位移的確定上提出新的方法,即由結(jié)構(gòu)受力反推得到的瞬時(shí)的適應(yīng)性的荷載分布模式和結(jié)合中國(guó)抗震規(guī)范反應(yīng)譜的能力譜法確定目標(biāo)位移的方法,同時(shí)提出一種新的循環(huán)往復(fù)加載的pushover應(yīng)用方法,并編制了專門的pushover分析應(yīng)用程序,應(yīng)用此程序?qū)Σ煌憷M(jìn)行分析,算例分析證實(shí)由結(jié)構(gòu)受力反推得到的瞬時(shí)的適應(yīng)性的荷載分布模式能夠較好的模擬地震過(guò)程中實(shí)際的結(jié)構(gòu)受力反應(yīng)情況,循環(huán)往復(fù)加載的pushover分析方法較單向加載的pushover分析更能準(zhǔn)確的反映實(shí)際的地震作用對(duì)結(jié)構(gòu)的影響。
