: Stress-related situations play a significant role in children’s lives and result in different reaction in children. Among various methods of evaluating the stressful environment of children, 54-item Children’s Coping Strategies Checklist-Revision1 (CCSC-R1) has been developed as one of the most powerful tools for assessing different aspects of coping in children.

In this paper, an attempt is made to examine the efficiency of an approximate incremental dynamic analysis (IDA) method to estimate the collapse capacity of conventional steel structures. To this purpose, two partially collapsed steel structures are selected. Both two structures are comprised of an ordinarymoment resisting frame systemin one direction, and a braced frame system in other perpendicular direction.

Post-earthquake observations showed that the use of URM buildings in the area with high relative hazard of seismicity lead to significant damages. Moreover, defects in design and construction of buildings, which was the result of the lack of enough supervision by responsible organizations, can be considered as other causes of damages. In this paper, observed damages in masonry buildings are presented and investigated in detail.

This building had much better performance than two others and experienced less loss. Moreover, the results of the analysis show that the collapse criteria related to the seismic evaluation codes are non-conservative. The results of this survey imply that the proposed method can precisely forecast the collapse or non-collapse of the studied buildings. Therefore, it would be recognized as a reliable method for collapse assessment.

This study indicates that concrete superstructures were more vulnerable than superstructures with steel girder. It also indicates that bridges with masonry abutments were more vulnerable than those with concrete abutments. Compared to single span bridges, the state of damage in multi-span bridges were more severe.

Considerable number of damaged buildings that are constructed in recent years, is probably because of the lack of enough supervision by IRCEO and other responsible organizations. In this paper, observed damages to RC structures were examined and explained in detail.

The greatest advantage of this method is its accuracy and rapidness. The EEW system issues several alarm messages during the course of one earthquake, improving the accuracy of the warning as the amount of available data increases. The EEWis transmitted to many kinds of devices and used for personal safety and automatic control. It is very important to observe strong motion in real-time using a dense network in order to improve the EEWsystem.

There is a good correlation between Coulomb stress changes and aftershocks distribution in Sarpol-e Zahab event. Furthermore, calculated static stress on the surrounding faults showed that middle part of the High Zagros Fault (HZF), the northern part of the Main Recent Fault (MRF), and the northern part of the Zagros Foredeep Fault (ZFF) are located in the positive stress change area.

In order to find out which level ofthe seismic design can be used in defining the fragility curves, different weights were considered to apply to the HAZUS fragility curves of high, moderate, low and pre-code to be used in the logic tree method. Finally, the mean and standard deviation values were introduced for the construction of fragility curves with the lognormal distribution for the seven Iranian building types.

In addition, the spatial stress variations were studied implementing the stresstensor inversion in different clusters of events. These results suggest that the 2017 mainshock ruptures caused both spatial and temporal stress perturbations that continued in time showing a specific character, which was not observed before in the Zagros region.

Thisinvestigation is based on the observations of IIEES reconnaissance team. The main objective of this research is to evaluate the seismic performance of reinforced concrete multistory buildings during the Sarpol-e Zahab earthquake and vulnerability assessments of important multistory reinforced concrete structures such as Mehr buildings of Sarpol-e Zahab, Eslamabad-e Gharb, and Imam Khomeini hospital in Eslamabad-e Gharb, Kermanshah Province.

In thisstudy, seismological aspects ofthe 2017 Sarpol-e Zahab earthquake has been investigated. The Sarpol-e Zahab earthquake, of magnitude 7.3 (Mw), occurred in southwestern Iran on November 12, 2017. Here, we investigated the properties of the strong ground motions of the earthquake using the records provided by Iranian Strong Motion Network (ISMN).
