Analysis of moisture-induced stresses in an FRP composites reinforced masonry structure

This paper conducts a numerical simulation of the antiseismic performance for single-layer masonry structures, completes a study on crack distributions and detailed characteristics of masonry structures, and finally verifies the correctness of the numerical model by experimental tests. This paper also provides a reinforced proposal to improve the antiseismic performance of single-layer masonry structures. Results prove that the original model suffers more serious damage than the reinforced model; in particular, longitudinal cracks appear on bottoms of two longitudinal walls in the original model, while these cracks appear later in the reinforced model; a lot of cracks appear on the door hole of the original model, and no crack appears in the reinforced model till the end of seismic waves; seismic damage of walls in the reinforced model is obviously lighter than that in the original model; dynamic responses at all observed points of the reinforced masonry are obviously less than those of the original model. Strains at all positions of the reinforced model are obviously smaller than those of the original model. From macroscopic and microscopic perspectives, the computational results prove that the reinforced proposal proposed in this paper can effectively improve the antiseismic performance of the masonry structure.

Reinforced Masonry

It is very important to develop reinforced block masonry structure system with a good anti-seismic performance and convenient construction. This paper mainly researched the displacement response of the reinforced masonry structure under earthquake. The maximum storey drift and displacement of the structure are calculated in Y direction by numerical analysis method.

The University

The University for Applied Sciences of Fribourg (UAS-FR) proceeded to theoretical and experimental studies on paraseismic strengthening of masonry walls. These studies aimed to develop new strengthening methods, mainly with Fibre-Reinforced Polymer (FRP) composite materials. The experimental studies analysed the behaviour of reinforced masonry walls under vertical load and horizontal static-cyclic load with various orientation of reinforcements. This study covers two kinds of FRP reinforcement: carbon sheet and carbon mesh.
