Thesis Topic Ideas: Earthquake-Resilient Low-Cost Housing for Rural Nepal
🎓 Academic Journey Progression Map
1. Introduction & Problem Statement
Overview: Structural analysis of affordable seismic retrofitting for traditional stone/mud houses post-2015 earthquake.
Background Context (Nepal): Rural housing in Nepal relies heavily on stone-in-mud masonry, which remains vulnerable to seismic events. Cost-effective retrofitting solutions using local materials enhance structural safety without prohibitive expense.
2. Research Objectives
- ›Perform finite element structural analysis (FEA) of unreinforced stone-and-mud masonry typologies
- ›Design low-cost seismic containment techniques using bamboo bands, wire mesh, and timber containment
- ›Evaluate stress distribution and drift capacity under simulated seismic ground motion
- ›Conduct cost estimation comparing retrofitting vs complete demolition and rebuilding
- ›Provide construction handbook for rural mason training compliant with NBC 105 structural codes
3. Proposed Methodology
- Field assessment of damaged and retrofitted stone masonry houses in Gorkha and Sindhupalchok
- Material strength testing (compressive strength of mud mortar and local stone samples)
- Finite Element Modeling using SAP2000 / ETABS / ANSYS software
- Pushover and non-linear dynamic time-history analysis using Gorkha earthquake motion records
- Economic cost-benefit analysis against National Reconstruction Authority guidelines
$ Worked Example / Sample Scenario
Sample Scenario: A 2-story stone-mud house in Gorkha is modeled in SAP2000 under simulated 7.8 Mw seismic shaking. Adding PP-band mesh encasement increases lateral load capacity by 38% while remaining under NPR 150,000 in material costs.

7. Frequently Asked Questions (FAQs)
Q: Is SAP2000 or ETABS better for modeling stone-mud masonry?
SAP2000 provides flexible non-linear link elements ideal for unreinforced masonry and retrofitting mesh analysis.
Q: What seismic ground motion data should I use?
You can use recorded accelerogram data from the 2015 Gorkha earthquake (KATNP station recording) for time-history analysis.
Q: Are physical shake table tests mandatory for a Master thesis?
No, rigorous numerical Finite Element Modeling (FEA) validated against published experimental literature is standard for M.E. theses.
Q: Where can I find Nepal's official building code guidelines?
The Department of Urban Development and Building Construction (DUDBC) publishes all NBC codes online.
