Abstract
With the addition of Chapter 6 Tsunami Loads and Effects in ASCE 7-16 Minimum Design Loads and Associated Criteria for Buildings and Other Structures, significant analytical effort will soon be required of structural engineers to ensure that susceptible buildings are appropriately designed and detailed to withstand tsunami loads. ASCE 7-16 Chapter 6 offers a prescriptive approach to analyzing these loads and effects, which is intentionally conservative, while also allowing for alternative performance-based analysis. Research into performance-based non-linear analysis for tsunami loading has been conducted by Baiguera, et al. (2020) using the software OpenSees, however this software is primarily used in academia and is not particularly prevalent in the private sector of structural engineering. This study presents a procedure for performing a similar non-linear static pushover analysis for tsunami loading in accordance with ASCE 7-16 using ETABS software. This thesis establishes that the use of the procedure described herein can assist in targeted strengthening of a building which can reduce construction costs while adhering to the strength capacity requirements of Chapter 6 of ASCE 7-16.
