Modelización de la Mampostería en el Comportamiento de un Edificio de Hormigón Armado /Modeling Of Masonry In The Behavior Of a Reinforced Concrete Building

The current design of the buildings is based on theoretical models that contemplate only the resistant structural elements. Enclosures and partitions in buildings are considered as non-structural elements. However, in the presence of an earthquake, they provide stiffness by modifying the magnitude and distribution of efforts. A more detailed analysis should consider the interaction of the masonry to consider the current structure behavior. The objective of this research was to synthetically develop a resistant earthquake analysis of a reinforced concrete building using Cypecad software, based on two theoretical models; the first one considers only the resistant elements; the other considers the interaction of the masonry non-structural with the building, using the Liauw & Kwan's mathematical model to calculate of the properties equivalent diagonal width (compression rod). The results obtained must be; The shear on the soft floor level is increased by an average of 21.5% according to the analysis directions "X" and "Y". The drift in the soft floor level increases 5.25%, with respect to the building considered with only resistant elements. The fundamental vibration period of the structure with the interaction of the uncracked masonry decreases by approximately 40% in contrast with the value obtained in the building considered with only resistant elements.
