ENERGETIC AND DYNAMIC ANALYSIS OF MODERN AND ORIGINAL MASONRY BUILDINGS.

The paper aims to emphasize the performance of confined masonry with polymer grids comparing to masonry with steel reinforcement, in terms of energy consumption, strength and stiffness. In the state-of-the-art there are two known types of masonry. The first type is the original brickwork, composed of burnt soil brick units bonded together with lime mortar. The second type is made of ceramic bricks burnt up to the point of vitrification, using cement mortar. There are important differences between the two types of masonry, which confer them different properties. Masonry is reinforced in order to increase its resistance to seismic activity. Original masonry can be reinforced with non-metallic, polymer-based reinforcements, while the modern masonry is reinforced with steel reinforcements. Energy consumption needed to produce a building will be carried out by calculating the embedded caloric energy that includes phases of production and transportation of materials: bricks, mortars and reinforcements. An ergonomic calculation will indicate the mechanical work needed for the construction of the two compared situations: original and modern reinforced brickworks. Increased elasticity and strengthen to earthquake in these two reinforcement situations is shown by a dynamic and modal analysis of structure with adequate software. The analysis will be made on two models taking into account requirement of seismic design code on plane and vertical irregularity. [ABSTRACT FROM AUTHOR]
