Seismic Performance and Seismic Design of Damage-Controlled Prestressed Concrete Building Structures

Abstract

A pesar del esfuerzo en investigación realizado para estructuras de concreto prefabricado con control de daño, existen muy pocas aplicaciones prácticas en edificios debido principalmente a la poca experiencia práctica y a los códigos de diseño que aún emplean filosofías convencionales. Esta tesis propone y valida un nuevo tipo de diseño sísmico para este tipo de estructuras. Para cumplir los objetivos de la tesis, diversos ensayos experimentales fueron realizados en estructuras de larga escala.

This dissertation aims to improve the understanding on the seismic performance of UPT walls by providing (1) extensive experimental data of the seismic performance of UPT walls, (2) experimental data on the ultimate behavior of UPT walls components, unbonded anchorage systems and external replaceable dampers, and (3) extensive numerical data to improve design methodologies and analytical tools. The primary objective of this dissertation is to propose and validate a performance-based design procedure for UPT walls with the aim of controlling the residual damage of precast concrete building subjected to large earthquakes. To this end, this research aims to extend the understanding of the experimental response, numerical modeling, and practical application of UPT walls implementing both internal and external replaceable dampers.
