Methods and technologies of seismic strengthening of buildings with brick walls

Abstract

Methods and instructions on the production technologies for the restoration and reinforcement of buildings with walls made of fired bricks, which have received various damages as a result of earthquakes, physical wear, and also have inconsistencies in space-planning and design solutions with the requirements of current regulatory documents, are given. The most typical types of damage to elements and structures of buildings as a result of earthquakes were identified and classified according to the results of analyzes of their consequences, in which the authors were directly involved (by the nature of their scientific and practical activities), as well as according to the analytical review of the relevant sources. The identification and compilation of classifications of the most common facts of inconsistency of space-planning and structural solutions with the requirements of the current design standards was carried out on the basis of the results of field inspections of the technical condition of numerous objects, the experience of which was accumulated by the authors over the past several years. Based on the results obtained, methods and technologies for seismic amplification of elements and structures of buildings have been developed, reflecting their features, composition and sequence of operations for the production of work, also based on the authors’ many years of experience in the implementation of similar developments, acquired during the implementation of a number of state scientific and technical programs, innovative projects and contractual work. For each of the considered cases and reinforcement options, the corresponding standards have been developed in relation to the labor intensity and cost of performing work, the recommended composition of the links and the corresponding standard set.
