The Study Of Earthquake Resistance Of Glass Fiber Sheet Reinforced Masonry Structure

Masonry structure seismic strengthening essence is by improving the structure of the power transmission way,improve the aseismic bearing capacity and ductility of the main component to resist lateral force,but also pay attention to ensure the integrity of the building,by enhancing connections between components in order to prevent the weak due to a strengthening of individual component parts of the transfer.At the same time,attention must be paid to strengthening the integrity of the building by strengthening the connection between components to prevent individual The strengthening of the components causes the transfer of weak parts.As a common building reinforcement measure,the composite fiber reinforced material has been researched by domestic and foreign scientific researchers.The mechanical properties of masonry bricks reinforced with glass fiber cloth have been summarized,and the bearing capacity and stiffness after reinforcement have been found.There is a certain degree of improvement,and there is bound the role of the expansion of the cracks in the masonry.The hysteresis curve,the skeleton curve and the stiffness degeneration curve of WS-1,WS-2,WS-3 and WS-4 were obtained.It is demonstrated that the Abiqus internal wall of brick masonry reinforcement The feasibility of analysis.For the reinforcement of masonry masonry structures,based on the reliability appraisal results,based on a thorough analysis of the stress conditions of the masonry masonry structure system and components after reinforcement,the technical level and construction site conditions of the construction team should be fully considered.Conduct a comprehensive analysis,select the specific reinforcement methods,so that the structure of the program technology is reliable,economical and reasonable,easy construction.The masonry masonry hybrid structure is not well-defined.Under lateral horizontal seismic forces,the contribution of different materials' bearing capacity and stiffness is inconsistent,causing the chain reaction of different components to break.Many earthquake disasters have proved that such structures often The damage is very serious,and it is impossible to guarantee the goal of seismic fortification with small earthquakes and strong earthquakes.Therefore,it is of significant engineering significance and theoretical significance to improve the seismic performance of traditional masonry masonry structures based on the traditional qualitative analysis of the typical damage characteristics.The glass fiber sheet is not only high in strength,but also light in weight and thin in thickness,and does not substantially increase the weight and cross-sectional dimension of the reinforcing member,and is widely applied to the reinforcement and anti-seismic reinforcement of buildings,bridges,tunnels and other structural types and structural shapes.And node structure reinforcement.Glass fiber reinforced sheet method of construction convenient construction,without large machinery,without on-site fixed facilities,less construction site occupation,construction work efficiency.Because it will not be embroidered,glass fiber sheet is very suitable for high acid,alkali,salt and atmospheric corrosion environment.
