The research shows that : 1 ) the ductility of the hsc bending members constructed is much greater than 5 ; 2 ) increasing the vertical links and distribution steel can increase the deflection under ultimate moment ; 3 ) with appropriate compressive bars , vertical links and distribution steel the increase of moment after yield and the decrease of moment under ultimate moment can be ignored , so the ductility of the hsc bending member is much larger ; 3 ) the width / depth ratio of hsc bending member has no obvious effect on the ultimate compressive strain of concrete ; 4 ) the method used here to calculate the deflection is applicable ; 5 ) the location of crack coincides with the location of vertical links and distribution steel ; 6 ) the bending property of the hsc structure under the blast load can meet the demand of protective engineering 研究表明:本文研究的梁、板构件的延性比远大于5 ;增加箍筋(钩筋、分布筋)含量,可以提高压区混凝土剥落时的挠度;在适当的受压筋、箍筋(钩筋、分布筋)含量下,可以忽略压区混凝土剥落瞬间的承载力下降,从而大大提高构件的延性;受弯构件的宽高比对压区混凝土极限应变的影响不明显;受弯构件的裂缝间距受箍筋(钩筋、分布筋)的布置影响;文中所用的承载力和变形计算方法是可行的。化爆试验表明,高强混凝土构件的动载抗弯性能能够满足防护结构的要求。
