GODINEZ DOMINGUEZ, Eber Alberto; TENA COLUNGA, Arturo  e  PEREZ ROCHA, Luis Eduardo. Comportamiento sísmico de edificios con base en marcos dúctiles de concreto reforzado con contraventeo chevrón. Ing. sísm [online]. 2012, n.86, pp.55-87. ISSN 0185-092X.

In this paper the authors summarize the results of a study devoted to evaluate, using nonlinear dynamic analyses, the seismic behavior of ductile moment-resisting reinforced concrete concentric braced frames structures (RC-MRCBFs) using chevron steel bracing (eight, 15 and 24 stories in height). RC-MRCBFs were assumed to be located in three different soil conditions in Mexico (coastline zone of the state of Guerrero and lakebed zones IIIa and IIIb of Mexico City). From the results obtained, it is possible to conclude that if capacity design principles and specific design parameters for the new design of RC-MRCBFs are used, suitable global ductility capacities and overstrength demands are obtained, and a satisfactory structural performance is achieved.
