Influence of the modular panels M2 on the resistant earthquake behavior of buildings

Abstract

The investigation consists of analyzing the influence of the modular panels M2 on the resistant earthquake behavior of buildings. In a 1st case: the M2 panel was considered as confined masonry and in a 2nd case: as floor systems (slabs). For this purpose, 5 different architectural projects located in Quito were used. Once the proposed systems have reached the earthquake resistant parameters established in the regulations, in a 1st case, the M2 modular panels are incorporated as confined masonry in buildings of 3, 6 and 9 floors. While, in a 2nd case, it was arranged that the modular panel M2 be considered as a floor system (slabs). Of these two groups of buildings with different layout of the panels, new values ​​of structural responses are determined, with whose data we proceed to compare with the results obtained with the contributed system. For the placement of the modular panels as masonry within the proposed structural systems, the equivalent strut method was used, where the walls work only axially under compression and do not absorb shear. While, for floor systems, the floor system with stell deck was used as a base model and another with the implementation of modular M2 panels. For this, two buildings of medium height (6 floors) and high height (16 floors) were available. From the structural analysis, for both cases: the systems contributed with modular M2 panels used both as confined masonry and floor systems (slabs), generated structural responses as periods and floor drifts lower than the system only contributed, because the modular panel M2 provides lateral stiffness and decreases the weight of the buildings, demonstrating that: structural vulnerability can be reduced and the structural behavior of.
