Abstract

With the frequent occurrence of earthquake disasters, the seismic strengthening technologies for existing building structures have become a research hotspot. This paper explores the development trends in this field, aiming to improve the seismic resistance of buildings and reduce the losses caused by earthquakes. The main problems existing in the current seismic strengthening technologies, such as material aging and high construction difficulty, are analyzed. Subsequently, several emerging strengthening technologies are introduced, including the application of high-performance concrete, the use of carbon fiber reinforced composites, and the integration of intelligent monitoring systems. These technologies not only improve the strengthening effect but also reduce the cost and construction period. Through continuous technological innovation and interdisciplinary cooperation, the seismic performance of existing buildings can be significantly enhanced.
