Abstract

INTRODUCTION Along with the development of the latest technologies in the construction of new structures, the reconstruction and major overhaul of existing buildings is also an important part of the construction complex, which needs improvement. One of the most common types of construction works performed during the renovation of buildings is the strengthening of reinforced concrete beam structures, namely: crossbars, floor slabs, coverings, beams, etc. Usually, in practice, to strengthen these structures, the following methods are used: increase in cross-section due to build-up; change of static scheme of work due to installation of tighteners, struts, racks, etc. 1 . However, sometimes the installation of additional, bulky, reinforcement designs is unacceptable because it causes changes in construction design and layout decisions of the interior space of the building at the same time significantly increasing the load on the bearings and the foundations. In this case, the method of reinforcing structures through external reinforcement is quite effective and advisable 2 . The principle of such

用外筋加固钢筋混凝土梁结构。效率研究

随着新结构建筑最新技术的发展，既有建筑的改造和大修也是建筑综合体的重要组成部分，需要改进。在楼宇翻新过程中，最常见的建筑工程之一是加固钢筋混凝土梁结构，即横梁、楼板、覆盖物、梁等。通常，在实践中，为了加强这些结构，使用以下方法:由于累积而增加截面;因安装绷紧器、支板、机架等导致工作静态方案改变然而，有时安装额外的，笨重的，加固设计是不可接受的，因为它会导致建筑内部空间的施工设计和布局决策的变化，同时显着增加轴承和基础上的载荷。在这种情况下，通过外部加固结构的方法是非常有效和可取的2。这样的原则
