Abstract
The current design of buildings is based on theoretical models that consider only the resistant structural elements. Building envelopes and partitions are considered as non-structural elements. However, in the presence of an earthquake, they provide stiffness by modifying the magnitude and distribution of forces. A more detailed analysis must consider the interaction of the masonry in order to consider the real behavior of the structure. The objective of this research was to synthetically develop a seismic resistant analysis of a reinforced concrete building using Cypecad software, by means of two theoretical models, the first one considering only the resistant elements, the other one with the interaction of the non-structural masonry with the building, using the mathematical model of Liauw & Kwan for the calculation of the properties of the equivalent diagonal (compression rod). From the results obtained, the shear at the soft floor level increases by an average of 21.5% according to the "X" and "Y" directions of analysis. The drift at the soft floor level increases by 5.25%, with respect to the building considered with only resisting elements. The fundamental period of vibration of the structure with the interaction of the uncracked masonry decreases by approximately 40% with respect to the value obtained in the building considered with only resisting elements.
