Abstract:	Increasing of seismic record in Brazil resulted in first Brazilian code of seismic NBR 15421:2006. Once publication succeed Brazilian sample building assessment must be developed in order to prevent or mitigate effects of horizontal accelerations from seismic. For preliminary screening of existent reinforced concrete structures qualitative Hirosawa method seems to be suitable to Brazilian reality. This paper aims to implement computationally seismic vulnerability assessment method in order to optimize assessments through opensource SMath Solver and programming language is C#. Adapted Hirosawa method compares resistance of building through seismic index of structure 𝐼𝑆 and Seismic demand index 𝐼𝑆0. Index 𝐼𝑆 is a product of indexes (Basic seismic index of structure, Irregularity index, Time index) and index 𝐼𝑆0 is formed by zone index, ground index and usage index. Model structure proposed by literature are analyzed in different levels of seismic acceleration as well as types of soil defined by Brazilian seismic code in order to demonstrate usability of tool. Graphical interface and results obtained from the application are showed aiding in decision-taking about new refined assessments or feasible interventions.
