The concrete strength of beam in the inclined compression zone is first made sure , the reducing coefficient " " of beam ' s concrete in the inclined compression zone is putting forward 首先確定了梁構件斜壓帶混凝土的強度,提出梁構件斜壓帶混凝土強度的折減系數。
Taking account of the two aspects , the concrete strength " fc " in the inclined compression zone which contributes to the shear capacity of columns is put forward 利用修正的桁架+拱抗剪機理,提出了柱的抗剪承載力理論公式,與試驗數據比較表西安建筑科技大學碩士學位論文頤口.面.
Two types of the equivalent mode of concrete compression zone were discussed and the corresponding formulae to calculate normal section strength of unbonded prestressed composite beams with reaction powder concrete were given . the calculating results tend to be conservative 結果表明,現有公式在計算rpc預應力疊合梁的斜截面開裂荷載及斜截面抗剪強度時,是偏于保守的。
