FEMA 310 Tier 1 seismic evaluation of existing building: A case study of a 7-story academic RC building of Jenderal Soedirman University, Indonesia

Abstract

A need to predict the seismic vulnerability of current buildings has led to a heightened interest in study that deals with seismic vulnerability assessment methods. The easiest and fastest method, known as a walk-down survey or a street survey, involves just the superficial information accumulated during a short inspection of a building. This paper picks a fairly new seven-story academic building made of reinforced concrete (RC) located at the Jenderal Soedriman University in Purwokerto, Indonesia, which was designed in 2015 using construction details illustrative of that exact period, for FEMA 310 Tier 1 assessment in the context of Performance-Based Earthquake Engineering (PBEE). Mandatory checklists as a role of the region of seismicity and the building’s level of performance are done. The outcomes after a procedure projected the building in the case-study demonstrated a range of possible flaws and seismic vulnerability. Therefore, detailed comprehensive evaluation is intensely endorsed.

Evaluation of seismic vulnerability assessment building using rapid visual screening method: case study at the Faculty of Islamic Economics and Business of Islamic State Prof. KH. Saifuddin Zuhri University

“…If the final score obtained is more than or equal to 2, then the building under review has a low vulnerability to earthquakes. However, if the building has an S value of less than 2, then the building has a high vulnerability to earthquakes and it is recommended to carry out further evaluation using the FEMA-310 guidelines [5].…”

Conventional RVS Methods for Seismic Risk Assessment for Estimating the Current Situation of Existing Buildings: A State-of-the-Art Review

“…As is stated in FEMA 310 [68], it is recommended that a rapid visual screening be performed using FEMA 154 and 155 (1988) before implementing this document. While FEMA 310 contains new types of buildings, the considered seismic probability of the exceedance was modified from 10 to 2% within 50 years, and the immediate occupancy performance class was included, in addition to the life safety performance class [68,74,75]. However, contradictions in the method have been discovered:…”

“…A building is referred to as a "benchmark building" if it is constructed to satisfy the specifications of the required design legislation and if this is implemented properly [74]. If a structure is designated as a "benchmark building", the structural examination step can be ignored [75,78]. The need for a detailed evaluation is decided after the first stage of the assessment process.…”
