Abstract

 Based on the practical needs of old residential community renovation projects under the background of urban renewal, this paper systematically reviews the current technical status of safety testing and appraisal for masonry structures, and deeply analyzes the prominent shortcomings and core problems in current testing methods, appraisal procedures, technical applications, and quality control. In combination with the material characteristics, aging patterns, and renovation-induced construction disturbance features of masonry structures, targeted testing technology optimization strategies and safety appraisal improvement paths are proposed from five dimensions: adaptive optimization of nondestructive testing technologies, construction of a multi-technology integrated testing system, refinement of safety appraisal standards, whole-process testing control, and empowerment through intelligent technologies. The research findings can effectively improve the accuracy, efficiency, and nondestructive performance of safety testing for masonry structures in old residential communities, accurately identify structural safety hazards, and provide technical support and practical references for scientific renovation, safety upgrading, and refined governance of old residential communities, thereby promoting the safe and high-quality advancement of urban renewal projects.
