Seismic Retrofitting and Structural Upgradation
Seismic retrofitting modifies existing structures to improve their earthquake resistance. This active research domain addresses older buildings designed before modern seismic codes. Projects focus on strengthening load-bearing elements, improving ductility, and ensuring energy dissipation during ground shaking.
Seismic Retrofitting of Buildings
This foundational topic covers techniques such as adding shear walls, steel bracing, and fiber-reinforced polymer (FRP) wraps to existing building frames. Students can analyze a case study building, perform a seismic assessment, and propose a retrofitting scheme. Key methods include:
- Steel bracing of RC frames for improving lateral stiffness
- Jacketing of columns and beams with concrete or steel
- Base isolation systems that decouple the building from ground motion
- Addition of energy dissipation devices such as dampers
- Strengthening of beam-column joints using FRP composites
Analysis for Seismic Retrofitting of Buildings
Beyond selecting techniques, detailed analytical study is essential. This project involves performing pushover analysis or time history analysis on an existing building model to quantify performance improvement after retrofitting. Tools such as ETABS, SAP2000, and ANSYS are commonly used.

This project involves analyzing the seismic response of different bridge types including simply supported girder bridges, continuous bridges, and cable-stayed bridges. Key parameters to investigate include pier height, bearing stiffness, and soil-structure interaction. Students can use response spectrum analysis or time history analysis to evaluate displacement demands and member forces.
Seismic Design Force for Single-Span Slab-Girder Skewed Bridges
Skewed bridges present unique challenges because their geometry causes torsional response during seismic excitation. This specialized project examines how skew angle affects the distribution of seismic design forces. Students can model bridges with varying skew angles (0, 15, 30, 45 degrees) and compare the resulting design forces, moment distributions, and support reactions.
Seismic Response of RC Frame Building with First Soft Storey
Soft storey buildings, where the ground floor has less stiffness than upper floors due to open spaces for parking or retail, are particularly vulnerable during earthquakes. This project analyzes the seismic response of such buildings and evaluates retrofitting strategies to mitigate the soft storey effect. Comparisons between bare frame, infilled frame, and retrofitted frame models provide insight into practical design decisions.
Seismic Behavior and Design of RC Shear Walls
Shear walls are vertical elements that provide lateral resistance to buildings. This project covers the design methodology for RC shear walls according to building codes such as ASCE 7 and ACI 318. Students can investigate the effect of wall thickness, reinforcement ratio, and wall aspect ratio on seismic performance. The project can also cover coupling beams between shear wall piers.
Calculation of Earthquake Actions on Building Structures
This project focuses on the fundamental calculation of seismic forces using code-specified methods. Students compute base shear, story forces, and overturning moments for example buildings using the equivalent lateral force procedure. Parameters such as seismic zone, soil type, importance factor, and response reduction factor are varied to understand their influence on design forces.
Earthquake Resistant Design and Construction Practices
Designing earthquake-resistant structures requires a holistic approach that integrates structural configuration, material selection, detailing, and construction quality. Project topics in this category help students understand how building codes and construction practices work together to achieve seismic resilience. Team coordination and site safety are essential aspects of these projects; see Workforce Management and Safety Practices for Civil Engineering for more on this topic.

Case studies of post-earthquake damage investigations can reveal how construction defects contributed to structural failures.
Role of Building Codes in Seismic Assessment
Building codes such as the International Building Code (IBC), Indian Standard IS 1893, and Eurocode 8 establish minimum requirements for seismic design. This project compares the seismic provisions across different codes and evaluates how they affect design outcomes for the same structure. Students can discuss the evolution of code provisions following major earthquakes.

Parameters such as band location, band width, and masonry material properties can be varied to develop design recommendations.
Response Spectrum Modelling for Regions Lacking Earthquake Records
Many regions around the world lack sufficient strong motion records for site-specific seismic hazard analysis. This project explores methods for developing design response spectra using probabilistic seismic hazard assessment (PSHA), attenuation relationships, and simulation-based approaches. Students can generate response spectra for a selected region and compare them with code-prescribed spectra to evaluate the adequacy of existing provisions.
Aspects of Earthquake Disaster Mitigation for Non-Engineered Construction
Non-engineered construction accounts for a significant portion of building stock in many developing countries and is particularly vulnerable during earthquakes. This project investigates low-cost mitigation strategies including the use of seismic bands, corner reinforcement, improved roof-to-wall connections, and appropriate building materials. Community-based approaches to earthquake preparedness and awareness are also relevant.

Energy dissipation devices reduce earthquake-induced damage by absorbing and dissipating a portion of the input energy. This project categorizes devices into passive, active, and semi-active systems. Students can model a structure with and without dampers using finite element software and compare the reduction in story drift, base shear, and acceleration response. Device types to consider include metallic dampers, viscoelastic dampers, fluid viscous dampers, and friction dampers.
