| 標(biāo)題 |
| 橢圓形截面墩柱承載力計(jì)算(51 卷) |
| 英文標(biāo)題 |
| Calculation of bearing capacity of pier-column with oval cross-section |
| 摘要 |
| 本文在參考矩形及圓形墩柱承載力計(jì)算方法的基礎(chǔ)上，根據(jù)混凝土受壓結(jié)構(gòu)正截面承載計(jì)算的基本假定，采用微積分原理，得到了橢圓環(huán)形截面柱在大偏心受壓情況下混凝土最大壓應(yīng)力及鋼筋應(yīng)力表達(dá)式。另外作為實(shí)心橢圓構(gòu)件其計(jì)算公式同樣適用。 |
