“…Hence, an enormous inter-storey drift ratio could have been experienced by this storey, thus causing severe damages. In a few cases of strong earthquakes, the soft-storey failure mechanism resulted in the total collapse of the bottom storey, as noted in the Kocaeli [65] and Sultandagi earthquakes in Turkey [66].…”

This paper presents a case study regarding failures of structural buildings which occurred in Malaysia after the first significant earthquake event dated on June 5, 2015. Ranau is a locality situated in Sabah, Malaysia on the island of Borneo. The seismic activity was triggered when an earthquake with a magnitude of 5.9 afflicted Ranau, including seven other districts that also felt the tremors. Even though the impact of magnitude was undisputedly not high, the severity level of damages was found to be absolute (irreparable) in the structural RC beam-column joints and soft-storey buildings. Most of the buildings in Malaysia were built without the consideration of seismic design, and thus a major factor in structural failure. The earthquake has directed the seismic demand, while the total displacement was concentrated at the weakest floor that caused more damage to the building. This paper shows the causes of beam-column joint damages and explains the proposed (to-date) strengthening methods. Future studies related to seismic activities are in need to analyse the performance of the existing design of structural RC members and propose seismic design in Malaysia.

“…In Turkey, a highly seismic zone, although the structural members in damaged buildings are generally designed in accordance with the standards and earthquake codes, implementation against the design and serious workmanship errors are frequently encountered in damaged buildings [35,[37][38][39][55][56][57][58]. In the aftermath of the Elazığ earthquake, similar implementation and workmanship errors have stood out.…”

In the Sivrice, Elazığ, Turkey earthquake on January 24, 2020, 41 people lost their lives, more than 1600 people were injured, 672 buildings collapsed, and around 12600 buildings were severely damaged due to poor construction quality. After such devastating earthquakes, damage assessment and forensic investigations are normally carried out quickly for a judicial process, and material qualities are revealed. However, emotional sensitivity of the victims in the earthquake affected zone and disruptions in key lifeline services such as transportation, electricity supply often make these processes difficult. After the Elazığ earthquake, along with the conventional in-situ core sampling method, concrete pieces were collected from columns of collapsed and severely damaged buildings and transported out of the earthquake zone to overcome these adverse conditions. Unlike in the conventional method where the whole sampling process is carried out in the earthquake zone, the core extraction from the transported concrete pieces was carried out outside the earthquake-affected area. The extracted concrete samples were checked for compliance with the prevailing material standards. Moreover, multiple reinforcing bars of various diameters were also extracted and tested to check their compliance with the standards. Besides, the results of examination of the quality of materials and workmanship used in the construction are also discussed, along with the precautions required to minimize fatalities and damage from similar buildings.

“…These collapses and severely damaged buildings are generally attributed to the low concrete grade, insufficient reinforcement detailing, inadequate workmanship, irregularities, etc. [3][4][5][6][7]. Although some buildings suffered moderate and minor damage only, this does not indicate that they have adequate strength and are safe for future earthquakes.…”

MVP interaction based seismic vulnerability assessment of RC buildings Consuming less time as compared to detailed evaluation techniques, preliminary seismic vulnerability assessments are widely utilized worldwide. In this paper, a new procedure called MVP Method (moment (M), shear (V) and axial (P)), is proposed to evaluate seismic performance of RC buildings. The procedure needs structural and architectural parameters and considers the interaction of moment, shear, and axial load capacities and demands. Simple equations are proposed for each capacity and demand so as to calculate the building performance score. The proposed procedure was verified on 192 buildings, and the success rate ranged from 86.5 to 89.1 %.
