Earthquake-Resilient Low-Cost Housing for Rural Nepal

Level: Master, PhDDifficulty: Advanced★ Popular Choice

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.
