摘要/Abstract

摘要：

为深入探究预应力钢板带加固技术在提升墙体承载力和降低变形程度方面的应用效果，探讨了支撑失效状态下预应力钢板带-砖砌体组合墙在施加荷载时的变形特性。在试验中，设计7个试件，均利用预应力钢板带实施加固，各自的加固情况不同。在试件制作中，实施底梁的浇筑后制作砖砌体墙，浇筑顶梁后对表面实施抹平处理，与底梁和砖砌体墙形成整体结构。将养护后的试件运至实验室中实施预应力钢板带加固。纵向钢板带的下料长度与墙体的高度保持一致。若需施加竖向预压应力，则下料长度会相应增加2或4 mm。横向钢板带与墙体的实际宽度相匹配。布设试验仪器与应变片并开始加载，直至组合墙体的支撑功能失效，停止试验加载。结果表明，墙体预应力钢板带的加固性能与墙体承载能力之间存在正相关关系；在墙体支撑失效前，曲线出现降低趋势，随后墙体支撑失效；较强加固性能的预应力钢板带可以降低墙体自身的应变值，即降低墙体自身的变形程度。预应力钢板带的应用能够显著增强墙体的整体刚度和稳定性。

Abstract:

To investigate the application effect of prestressed steel plate strip reinforcement technology in improving the load-bearing capacity of walls and reducing the degree of deformation， the deformation characteristics of prestressed steel plate strip brick masonry composite walls under applied loads were investigated by considering the failure state of supports.In the experiment， 7 specimens were carefully designed and reinforced with prestressed steel plates， each with different reinforcement situations. In the production of specimens， after pouring the bottom beam， a brick masonry wall is made. After pouring the top beam， the surface is smoothed to form an overall structure with the bottom beam and brick masonry wall. Transport the cured specimens to the laboratory for reinforcement with prestressed steel plates. The cutting length of the longitudinal steel plate strip should be consistent with the height of the wall. If vertical preloading stress is required， the cutting length will correspondingly increase by 2 or 4 mm. The horizontal steel plate strip matches the actual width of the wall. Install testing instruments and strain gauges， start loading until the support function of the composite wall fails， and stop the test loading.The results demonstrate a positive correlation between the reinforcement performance of prestressed steel plate strips on walls and the load-bearing capacity of the walls. Before the wall support fails， the curve shows a decreasing trend， followed by the failure of the wall support. A prestressed steel plate strip with strong reinforcement performance can reduce the strain value of the wall itself， that is， reduce the degree of deformation of the wall itself. The application of prestressed steel plate strips can significantly enhance the overall stiffness and stability of walls.

Key words: support failure, pre stressed steel plate strip, bottom beam, top beam, brick masonry walls, composite wall, wall deformation characteristics
