Earthquake-resistant behavior of three mid-rise buildings designed according venezuelan seismic codes

Here is presented a study on the seismic vulnerability of three mid-rise structural models projected according to Venezuelan seismic code Covenin 1756-01. Models have similar structural configurations in plant and in inter-story heights. Seismic action uses hybrid accelerograms compatible with t...

Los modelos tienen similares configuraciones en planta y en alturas de entrepiso; en la acción sísmica se utilizaron acelerogramas híbridos, compatibles con el espectro de diseño característico de la zona metropolitana Barquisimeto-Cabudare. El daño se evaluó mediante curvas de fragilidad e índices de daño, incluido el enfoque probabilista. Algunos modelos mostraron altas probabilidades de daño severo o colapso, sufriendo deformaciones laterales y degradaciones de rigidez significativas más allá de límites aceptables normativos, evidenciando que los desplazamientos relativos, y la rigidez son indicadores fundamentales del daño estructural. Se concluyó que para evaluar el comportamiento de los modelos estructurales analizados, sometidos a la acción sísmica probable, se requiere de un detallado estudio de los desplazamientos horizontales, particularmente de los desplazamientos relativos entre niveles, y que las previsiones de la norma venezolana podrían no ser suficientes para la evaluación del desempeño sísmico de estos modelos Universidad Centroccidental Lisandro Alvarado - Decanato de Ingeniería Civil 2016-01-15 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Artículo científico de investigación original application/pdf https://revistas.uclave.org/index.php/gt/article/view/1255 10.13140/RG.2.1.5031.7687 Gaceta Técnica; Vol. 14 No. 1 (2015): July-December; 33-55 Gaceta Técnica; Vol. 14 Núm. 1 (2015): Julio- Diciembre; 33-55 Gaceta Técnica; v. 14 n. 1 (2015): July-December; 33-55 2477-9539 spa https://revistas.uclave.org/index.php/gt/article/view/1255/557
