Abstract

Abstract This article presents the materials of deformability studies of pre-stressed steel-concrete beams reinforced with a package of reinforcement with different ratio of tape and rebar in the pure bending moment zone. The aim of the research was determination of the reinforcement percentage influence, for pre-stressed reinforced concrete beams reinforced with a package of reinforcement on their deformability. Also, the aim was to evaluate the effectiveness of using pre-stressed rebar in combined reinforcement. The practical significance of the experimental research is to study the deformability in pre-stressed bending elements with external tape and rebar reinforcement, taking into account the influence of different ratios of reinforcement areas within the combined reinforcement and development of proposals for such structures` calculation and design. The scientific novelty of the research is in obtaining the deformability characteristics of reinforced concrete beams reinforced with a package of reinforcement (tape and steel bars with periodic profile) with different ratios in the case of static loads` action.

无应力钢筋配筋率对预应力RC梁变形性能的影响

本文介绍了在纯弯矩区用不同带筋比的钢筋包加固预应力钢-混凝土梁的变形能力研究材料。研究的目的是确定钢筋百分比对预应力钢筋混凝土梁变形能力的影响。此外，目的是评估预应力钢筋在组合加固中的有效性。试验研究的实际意义是研究带外钢筋的预应力弯曲构件的变形能力，同时考虑组合钢筋内不同配筋面积比的影响，并为此类结构的计算和设计提出建议。这项研究的科学新颖之处在于获得了在静载荷作用下，用不同比例的钢筋（带和周期性截面钢筋）加固的钢筋混凝土梁的变形特性。
