Abstract

In view of potential vulnerability of even exciting buildings designed based on seismic design codes under consecutive strong earthquakes, paying attention to the use of a secure system, especially in earthquake-prone regions is revealed. Tunnel form system is a new industrial construction system in which only the slabs and walls are used as lateral load resisting elements (Balkaya and Kalkan, 2004). Naming this system as the tunnel form is due to the installation of formworks in box manner (Fig. 1) (Mirghaderi et al., 2009).
Previous earthquake experience and the results of laboratory and numerical studies of lateral resistance of tunnel form construction represent a very significant performance against strong earthquakes. So far no study has been conducted to assess the resistance of this construction system subjected to consecutive earthquakes. It seems that this structural system is able to retain safety against successive earthquakes. This study aims to quantify the post-earthquake capacity of the damaged tunnel form buildings after subjecting the main shock and also their performance assessment subjected to multiple earthquakes.
