In the present investigation, the effects of irregularity in plan (entering corners) on the seismic evaluation of porched buildings of 1 to 5 levels with rectangular, cross, U, L, T and O, located in the city of Cusco (specifically in the district of San Jerónimo), in relation to compliance with Technical Standard E.030 Earthquake-resistant Design of 2018 for soil profiles S1, S2 and S3, for this an analysis was made for irregularity both in height and in plan being the main irregularity that of the incoming corner. Using the method of static analysis or equivalent forces and the spectral modal dynamic analysis, the seismic evaluation of the buildings was made, which are divided into 3 groups as follows: realself-built buildings in the shape of L, U and rectangular, buildings Propuesta with real measurements and propuesta buildings optimized with rectangular, cross, U, L, T and O shapes. The propuesta buildings of rectangular shape, cross, U, L, T and O were modeled based on measurements taken in the field of real buildings, measurements pertaining to mezzanine heights, distance between columns, structural elements such as 0.25 mx 0.45 m columns , Beams of 0.25 mx 0.40 m and slab height of 0.20 m, to verify if they comply with Technical Standard E.030 of the year 2018, calculating vibration period parameters, basal shear, dynamic shear, minimum shear, displacements and mezzanine drifts. Propuesta buildings optimized with 0.45 mx 0.45 m central and perimeter columns, 0.25 mx 0.50 m L-shaped corner columns, 0.30 mx 0.45 m main and secondary beams and 0.20 m slab height are modeled as a result of real and propuesta buildings with real measurements do not meet the parameters of mezzanine distortion limits, so, as a solution to reduce excessive absolute displacements, these new dimensions of beams and columns are established with which new irregular buildings are modeled. 1 to 5 levels of rectangular shape, cross, U, L, T and O, for profiles of soils S1 (rock or very rigid soils), S2 (intermediate soils), S3 (soft soils), with ETABS software taking in I also consider irregularity analysis. Likewise, the modeling of buildings contributed by means of the solid-type finite element method is performed in the SAP2000 software to verify in which part of the building there is a greater concentration of efforts, this type of finite elements is done by discretizing the building in a finite amount of elements (cubes), in which you can verify with different colors the variations of axial stresses, traction and compression that result from the application of the pseudo-acceleration spectrum to the building, which serves to see where in the building it is they give the greatest tensile and compression stresses as well as their distribution and variation. The presence of the incoming corner influences the seismic evaluation of the buildings contributed real, propuesta with real measures and optimized propuestas, with respect to torsional irregularity and increased absolute maximum displacements, which can be reduced by complying with Technical Standard E. 030 of the year 2018, through the increase of the area of columns and beams and the implementation of L-shaped columns in the corners of the buildings. The propuesta buildings optimized from 1 to 5 levels in rectangular, cross, U, L, T and O shape meet the mezzanine distortion limits for all floor profiles since the beams are 0.30x0.45 m, central columns and eccentric of 0.45x0.45 m, L-shaped column of 0.25x0.50 m and slab height of 0.20 m. Likewise, it was determined that by means of the solid-type finite element method, the distribution of maximum tensile and compressive stresses in the interior incoming corners of the propuesta buildings located in the district of San Jerónimo, province and department of Cusco can be observed.
