摘要:
为研究钢管再生大骨料自密实混凝土构件的受弯性能,以再生骨科强度、再生骨料粒径、含钢率为参数,设计制作了8根受弯构件,并对其进行了试验研究.研究表明:再生大骨料强度和粒径对钢管再生大骨料自密实混凝土构件受弯承载力影响较小; 含钢率对钢管再生大骨料自密实混凝土构件受弯承载力影响显著,当含钢率提高20.3%时,极限抗弯承载力提高了13.15%; 当含钢率提高56.1%时,极限抗弯承载力提高了31.21%; 就钢管再生大骨料自密实混凝土纯弯构件而言,本文给出的极限抗弯承载力计算公式与试验值吻合度良好,可以用于该种构件的设计.
Abstract:
In order to study the flexural performance of steel tube recycled large aggregate self-compacting concrete, 8 flexural specimens were designed and manufactured based on the parameters of recycled concrete strength, recycled aggregate particle size, and steel content, and the experimental study was conducted. Studies show that the strength and particle size of recycled large aggregates have little effect on the flexural bearing capacity of steel pipe recycled large aggregate self-compacting concrete; the steel content has a significant effect on the flexural bearing capacity of steel pipe recycled large-aggregate self-compacting concrete. When the steel content increases by 20.3%, the ultimate flexural bearing capacity increases by 13.15%; when the steel content increases by 56.1%, the ultimate flexural bearing capacity increases by 31.21%. For steel tube recycled large aggregate self-compacting concrete pure flexural members, the calculation formula of ultimate flexural capacity given in this paper is in good agreement with the experimental value, and can be used for the design of this kind of member.
