cranes-design principles for loads and load combinations 起重機(jī).負(fù)載和負(fù)載組合的設(shè)計(jì)原則
5 . utilizing the grey clustering method, mathematics and mechanics knowledge, the safety states of dams under typical load combinations are analyzed and evaluated . 6 利用灰色系統(tǒng)中的灰色聚類方法,并結(jié)合數(shù)學(xué)、力學(xué)知識(shí),對(duì)大壩在各種荷載組合作用下的安全性態(tài)作了分評(píng)價(jià)。
due to the complexity of the load combinations of the gate chamber, it is difficult to perform such test on each load case . on the other hand, it is lack of the test data on the load case perpendicular to the current direction of the gate frusta till now 由于閘室的受力荷載組合較為復(fù)雜,對(duì)每種工況都做光彈試驗(yàn)不容易做到,且有關(guān)垂直水流方向的閘墩受力狀況的試驗(yàn)資料迄今尚很缺乏。
in this paper, load effect combination, resisting buoyancy of basement, load combination of basement outer wall and basement soleplate and equivalent uniform live load of fire engine basing on " load code for the design of building structures " are discussed 摘要該文探討的是《建筑結(jié)構(gòu)荷載規(guī)范》中有關(guān)荷載效應(yīng)控制的組合、地下室抗浮、地下室外墻和底板的荷載組合以及消防車等效均布荷載的確定等內(nèi)容。
finally, niutoushan double-curvature arch dam was modeled and 3-d fem simulation analysis was performed, so as to find out the integral safety factor and the stress and displacement patterns of dam and its foundation under different load combination 最后,對(duì)牛頭山水電站雙曲拱壩進(jìn)行了有限元建模和三維非線性有限元仿真分析,計(jì)算分析了各種情況下壩體和基巖的應(yīng)力位移規(guī)律,對(duì)大壩的整體安全度進(jìn)行了綜合評(píng)判。
