EFFICIENCY IN STRUCTURAL DESIGN. AN APPLICATION EXERCISE IN EARTHQUAKE RESISTANT IN MASONRY CONSTRUCTIONS.

Abstract

The irregularity of the spatial configuration of the buildings increases the damaging effects of torsion on the resistant planes, increasing efforts, and consequently oversizing the structure. Given this problem, the ARGENTINE REGULATION FOR SISMORRESISTENT CONSTRUCTIONS, Part I, for constructions in general (INPRES - CIRSOC 103 - 2013), incorporates quantitative criteria that added to the existing qualitative criteria, allow the evaluation of torsional irregularity from a three-dimensional analysis. During the design process of an architectural work, a synthesis of the functional, technological and formal conditions is generated, as the structural mechanism is one of these conditions, it must be conceived by the designer from the early stages of the creative process. In the course of Structures III, a design exercise with seismic-resistant structural chained masonry is carried out, considering efficiency as a fundamental aspect of the evaluation of the proposal. The student is oriented to design the structural mechanism and recognize the actions on it and throug the use of computer resources, generate a three-dimensional model for analysis, verification and reformulation, in order to achieve an efficient result. Experiences of student design are detailed, where the criteria and ability to evaluate alternatives of structural mechanisms are verified, in this search for structural efficiency.
