In this thesis, comparative parametric analyses were carried out, in matter of seismic behavior, to assess the incidence that the incorporation of Conic Section Haunched Beams have on conventional reinforced concrete Framed and Dual structural systems disposed by the Peruvian code E.030 (2020). Study that had as test object, a multi-story building of eight levels for housing purposes, located in the city of Cusco and called “Residencial Kala”. In that way, 90 hypothetical test cases were inscribed, where each proposal of structuration differed accordingly whether 1) its haunched beam profiles were Circular, Elliptical or Parabolic; 2) their haunch depths; 3) haunched beams locations inside the system; and 4) the existence (or not) of shear walls. On the other hand, the two control cases for conventional systems were modeled as well. Subsequently, structured specimens were subjected to Modal Spectral Structural Analyses by the Finite Element Method brought out by the computational package ARSAP 2022. These analyses were adjusted to the dictated procedures and properties by the Peruvian codes E.020: Loads; E.030: Seismic-resistant design; and E.060: Reinforced concrete. Thus, legit formulated calculations were restricted to lineal-elastic behaviors both mechanically and geometrically, being approximated into plastic behaviors according to those design codes. Consequently, results showed that the incorporation of these types of Non-prismatic Beams in both systems, lead to Base Shears, Overturning Moments and Torsions increments up to 133.7%, 134.8% and 95.0%; respectively, in the most critical direction of analysis. Nevertheless, in that same seismic direction (X), important stiffness increases were found, in function of Drifts and Maximum Pseudo-plastic Displacement reductions, down to 59.8% and 70.6%, respectively. In regards of structural irregularities caused by their inclusion, augmentations up to 22.2% on Torsional Irregularity Indices were reported inside the Dual systems comparation, but also diminishments down to 8.1% inside the Framed systems comparation. Continually, decrements on Vibration Periods were detected, for percental values down to 62.0% on Framed cases, and 52.3% for Dual cases. Finally, in function of Structural Weights, it was obtained that non-conventional systems proposed could allow discounts down to 2.4% for Dual systems, but additions up to 16.8% for Framed systems.
