This paper try to mix the finite strip method and hybrid stress element , and deduce a numerical and computer method which combines the advantages of the two methods - mixed hybrid finite strip method ; analyze the intensity and stability of the orthotropic plate by this method ; deduce the formula of the orthotropic plate ' s analysis and calculation under this method ; compile the program of orthotropic plate ' s mixed hybrid finite strip method ( hfsop . for ) with fortran - 77 language , and perform them under fortran90 environment of pc computer ; comparing with traditional methods by example of computing , prove that the mixed hybrid finite strip method have better degree of accuracy , moderating the stiffness of plate , coming more close to actual conditions , avoiding over - hard or over - soft ; finally , this paper analyze the stability of a orthotropic plate by this method , and deduce the - value of critical stress 論文將有限條法和應(yīng)力雜交元法兩者結(jié)合起來(lái),導(dǎo)出一種兼有兩者優(yōu)點(diǎn)的數(shù)值計(jì)算方法? ?混合雜交有限條法。運(yùn)用這種方法對(duì)正交異性板的強(qiáng)度和穩(wěn)定進(jìn)行了分析,推導(dǎo)出正交異性板在這種方法下的分析計(jì)算公式,用fortran - 77語(yǔ)言編寫(xiě)正交異性板混合雜交有限條法程序( hfsop . for )在微機(jī)fortran90環(huán)境下運(yùn)行。通過(guò)算例與傳統(tǒng)的方法比較,驗(yàn)證混合雜交有限條法有更好的精度,使板的剛度適中,更接近實(shí)際情況,避免“過(guò)硬”或“過(guò)軟” ;最后,論文還用此方法對(duì)一正交異性板進(jìn)行了穩(wěn)定分析,得出臨界應(yīng)力值。
In addition , the computer method is proposed to get the stochastic pile capacity and the random optimum analysis is done in virtue of the genetic algorithm which can easily think over the influence of the randomness of pile capacity on the internal force of capping beam based on the thorough analysis about the primary factors influencing the randomness of pile capacity . an optimization program is worked out for the analysis which can consider the pile - soil - cap interaction and the non - linear character of the foundation soil 此外,本文對(duì)影響基樁承載力差異性的主要因素進(jìn)行了深入分析,提出了基樁承載力隨機(jī)生成的計(jì)算機(jī)方法,并采用遺傳算法對(duì)承臺(tái)梁內(nèi)力進(jìn)行隨機(jī)優(yōu)化分析,可方便地考慮基樁承載力隨機(jī)性對(duì)承臺(tái)梁內(nèi)力的影響,并開(kāi)發(fā)出能考慮樁?土?承臺(tái)共同工作及地基土非線性特性的樁基承臺(tái)梁內(nèi)力優(yōu)化分析程序。
In this paper , with the available computer method , theauthors have obtained the stress distribution acrosssections of reinforced concrete composite beams under two stages ofloading , and show that the stress redistribution under two stages ofloading results in a reduction of stress discrepancy in thetensile steel and of strain discrepency in the compressed concrete between thecomposite beam and the corresponding casting beam 本文運(yùn)用成熟的電算模擬方法,計(jì)算得到二階段受力鋼筋砼疊合梁在不同受力階段的截面應(yīng)力分布規(guī)律及鋼筋的應(yīng)力變化規(guī)律,分析得到二階段受力時(shí)鋼筋砼疊合梁1的受拉鋼筋應(yīng)力超前、受壓區(qū)砼應(yīng)變遲后逐漸緩解的實(shí)質(zhì)為截面應(yīng)力重分布的結(jié)果
