A Simple Strengthening Method for Preventing Collapsed of Vulnerable Masonry Infills

چکیده
A series of structural tests were conducted to examine the seismic performance masonry infills strengthened with particular materials on infilled reinforced concrete (RC) frame structures. Six 1:4 scaled-down RC specimens had been prepared, including one brick-infilled without strengthening and five brick innovative materials. The steel wire mesh, chicken hexagonal plastic fiber-reinforced polymer (FRP), stretch film. was diagonally applied both surfaces infill. mesh sewn using wire, while FRP sheet glued epoxy resin film synthetic rubber adhesive. tested following FEMA 461 standard testing protocol, which involved applying lateral static cyclic loading specimens. displacement transducer apparatus measured deformations specimens, crack propagation observed during experimental works. results showed that most exhibited an increase in their strength, secant stiffness, deformation capacity, energy dissipation. Among all prepared specimen best promising results, i.e., long steady strength after yielding. This result suggests for can ductility performance. It is expected withstand earthquake shaking, has low application costs, feasible even by unskilled local laborers.

Efficiency of strengthening techniques assessed for existing masonry buildings
The Azores archipelago is a zone with a vast cultural heritage, presenting a building stock mainly constructed in traditional stone masonry. It is known that this type of construction exhibits poor behaviour under seismic excitations; however it is extensively used in seismic prone areas, such as this case. The 9th of July of 1998 earthquake was the last seismic event in the islands, leaving ma...
متن کاملNew Frp and Adhesive Materials for Strengthening Infill Masonry Structures
ABSTRACT: This paper explores the behavior of infill masonry structures strengthened with a new type of Fiber Reinforced Polymer (FRP) strengthening system with high fracture strain know as PET (Polyethylene Teraphthalate) and a new near-surface mounted (NSM) Carbon fiber strengthening system using a cementitious material as the adhesive as compared to a Glass Fiber (GFRP) strengthening system ...

Radioiodinated meta iodobenzylguanidine (MIBG) is one of the important radiopharmaceuticals in Nuclear Medicine. [123/131I]MIBG is used for imaging of Adrenal medulla, studying heart sympathetic nerves, treatment of pheochromacytoma and neuroblastoma. For clinical application, radioiodinated MIBG is prepared through isotopic exchange method, which includes replacement of radioactive iodine in a...
متن کاملInfluence of Masonry Infills Walls on the Seismic Behaviour of Multi-storey Waffle Slabs Rc Buildings
In this work, we analyze the influence of masonry infill walls on the seismic performance of waffle slabs reinforced concrete (RC) framed structures. We analyze buildings of three, five and eight storeys, which are representative for a big number of housings in Barcelona, Spain. Capacity spectra have been obtained by performing pushover analyses and we have used a simplified procedure to obtain...
