Abstract
As studies have been conducted on structures exposed to earthquake or other similar destructive events revealed, implementation problems during construction have led to slight, serious and irrevocable damage. Meanwhile, with respect to various sensitive and subtle details, implementing concrete structures have not been excluded from this principle or are involved with these problem’s consequences. The present study investigated the relation between ductility and energy absorption, especially when the imposed lateral load is alternative. Also, the issue of energy-taking and input energy dissipation in a structure implemented according to international standards details of reinforced was studied. Furthermore, by implementing damage index model based on hysteric energy theory, three index levels including elemental, stratified and general structure damage were presented and the importance of precisely implementing regulation details were interpreted. Moreover, ductility and energy absorption level in tall structures’ load revisiting systems as well as structures’ non-linear behavior causes were explained. Since this case study focused on bending frame system and shear wall and analyzed total deformation of structures constituting shear wall and rigid frame. The research findings can be useful to determine the effect of implementing international standards details of reinforced concrete buildings on ductility and energy absorption of structure.
Highlights
Mistakes and defects occurred during implementing projects may cause some damages such as fracture, empty additional spaces, or contaminated concrete, which all lead to serious problems
The standard structural details employed in the building skeleton have been analyzed. Observing these details have caused to the increase of ductility in the structure and its resistance against earthquake
The research findings indicate that the damage imposed to the structures is low, the damage distribution diagrams and hysteretic energy in stories indicate the focus on damage and energy in one or more stories
Summary
Mistakes and defects occurred during implementing projects may cause some damages such as fracture, empty additional spaces, or contaminated concrete, which all lead to serious problems. The standard structural details employed in the building skeleton have been analyzed Observing these details have caused to the increase of ductility in the structure and its resistance against earthquake. Absorbability and energy dissipation can be specified by investigating non-linear and inelastic behavior of structure Their behavior is precisely implementing building details during construction. Akiama (1985) studied limit state design of structures and attempted to explain the primary principles of energy method using the method proposed by Huesner. Bertro and Yuang can be considered as pioneers whose studies caused other researchers to conduct more analyses in this regard They proposed that using input energy as a base for selecting design earthquakes can be useful. Occurring destructive earthquakes during the recent decades as well as developing research methods and experimental facilities, it has been proved that the increase of structure strength as a single design parameter in traditional method cannot supply adequate safety by itself or decrease structural damage
