Abstract
Analizar las condiciones y características de diseño y comportamiento en estructuras tipo puente, se considera fundamental dada su relevancia para facilitar el transporte de productos, traslados, desplazamientos y en general por facilitar la condición humana. El artículo reporta los desplazamientos por carga lateral sísmica en una estructura tipo puente, al estar sometidos el puente a excitación sísmica, su seguridad estructural es vulnerable ante la presencia de carga lateral tanto en su superestructura como en su infraestructura, influyendo en su integridad estructural, para su análisis su usa la metodología del trabajo virtual, los resultados del análisis de los desplazamientos por carga lateral, denota en porcentaje de 45 % de su colapso, al recibir el primer impulso de carga lateral en la cubierta del puente y con una probabilidad de falla en un 67%, lo anterior con base en el análisis, reflexión y síntesis aplicados. Más investigación es necesaria, empleando otras herramientas para evaluar y comparar los resultados obtenidos y así enriquecer el proceso.
Analyzing the conditions and characteristics of design and behavior in bridge structures, is considered fundamental given its relevance to facilitate the transport of products, transfers, movements and in general to facilitate the human condition. The article reports the displacements by lateral seismic load in a bridge type structure, when the bridge is subject to seismic excitation, its structural safety is vulnerable to the presence of lateral load both in its superstructure and in its infrastructure, influencing its structural integrity, for its analysis, it uses the methodology of virtual work, the results of the analysis of the displacements by lateral load, it denotes in 45% percentage of its collapse, when receiving the first impulse of lateral load in the deck of the bridge and with a probability of fails by 67%, the above based on the analysis, reflection and synthesis applied. More research is necessary, using other tools to evaluate and compare the results obtained and thus enrich the process.
