Innovation in Teaching and Learning

  • 15CVL302: Design of Concrete Structures
    Students were given a term project in which they have to visit a construction site and collect information like footing details, reinforcement details, estimation details, structural details. They were asked to make a presentation using the data collected. Students were tested for their understanding about the differences and importance of the theoretical structural knowledge over practical knowledge. A report was submitted by team of 5 or 6 students at the end of the semester. The entire exercise was considered as a term project.
    Students were also asked to construct a standard macros excel sheet templates for designing simple structural elements like beams , columns, slabs and dog legged stair cases as a part of the term project.
  • CVL480: Construction Management
    Primavera - a project management software tool was taught to the students in the class. A hands on training was given for every students working on their personal laptops for about 8 teaching hours with the help of projector. A term project on 'scheduling and planning of a construction of a simple building' using Primavera was given to the students. The term project was given higher weightage in their internal marks.
  • MNG400: Principles of Management
    An exposure to startup ideas, incubators in India was given to the students. Students were asked to do a preliminary market survey and methodology framing for any start-up idea of their choices, as a term project which was higher weightage in their Internal marks. Students were grouped into 10-15 teams depending on the class strength. An insight about forming a Detailed Project Report (DPR) was also taught in the class. Best DPR reports were chosen and guided to competition held by Business incubators in South India.
    2013-2017 Batch: One of the student team (Cashless credit cards) bagged a spot in "top 30 startup idea" organised by Amrita Technology Business Incubator. Also the startup model was implemented in the university's cultural fest ANOKHA 2017. Team members: Akhil reddy & Akshay Reddy. 2014-2018 Batch: One of the student team has successfully registered a Private limited company based on their DPR on the theme "Solid waste Management". Team Members: Koushik Raj & Gowtham Raj

With increase in quantities of industrial bi-products, solid waste management is of special significance. Approximately two million tons of Waste Foundry Sand (WFS) is produced yearly in India. Improper disposal of waste foundry sand impose environmental effects such as inhibition of soil microbial activity and ground water toxication. Using WFS as a building materials can effectively reduce the environmental effects and disposal concerns. Strength requirements and cost reduction is achieved by partially replacing cement with fly ash. Polypropylene fibre increases the ductility of the concrete. In this paper, work behaviour of M25 concrete was studied by replacing natural sand with WFS (10%, 20% and 30%) by weight, cement with fly ash(20%, 25% and 30%) by weight and polypropylene fibre was added (0.5%, 1% and 1.5%) by weight of cement. The mix proportion parameters of the concrete were analysed using Taguchi method for optimal design of experiments. Concrete mixtures were designed in L9 orthogonal array with three control factors namely WFS, fly ash and polypropylene fibre. The mixtures were tested both in fresh and harden state, and the optimized mixture was identified based on the test results using Signal to Noise ratio. © 2018 Elsevier Ltd.

Indian cities are expanding not only in terms of built environment but also in population. Multi-story buildings are rising rapidly to accommodate the growing population, undesirably even in hazard prone areas. Such a scenario calls for a proper disaster risk reduction program and plan to control the inevitable damage to lives and properties. Earthquakes are destructive only if the factors that increase the damages prevail. Attention should be given to crowded cities with people and infrastructure vulnerable to hazard. This study presents the details of deterministic seismic hazard analysis (DSHA) done for Coimbatore city of the state of Tamil Nadu, India using the latest available information on seismicity of the region. The earthquake data was compiled from different agencies and homogenized in a unified moment magnitude scale to create an updated earthquake catalog. Seismotectonic map for the study area was prepared by superimposing the earthquake events on the seismogenic sources. DSHA was then performed by dividing the study area into grids of size 0.02º × 0.02º (approximately 2 km × 2 km) using a MATLAB code, considering three different attenuation relationships for the stable continental region. Land use (LU) map for the region was developed from LANDSAT 8 data using various GIS platforms. Hazard contour map prepared using ArcGIS, was then overlaid on the LU map to comprehend the seismic risk of the region. It was observed that, though the wards south-west of the city shows higher Peak Ground Acceleration (PGA) values, the wards north-east of the city have larger and denser built-up areas, increasing its vulnerability, in the event of an earthquake.

Dr. Sreevalsa Kolathayar, Divakar, S., and Lalith Prakash E., “Land Use Exposure to Deterministic Seismic Hazard in Delhi National Capital Territory”, Proceedings of the Geotechnical Earthquake Engineering and Soil Dynamics V. pp. 135-145, 2018.[Abstract]


Indian cities are growing at a faster rate due to urban sprawl and urban dynamics. Delhi is one of the seismic hazard-prone cities in the world located next to the Himalayan range, home of nearly eighteen million. Construction of high rise buildings even in the hazard-prone areas has become common due to high population intensity in major Indian cities. Damages to the livelihood and lives happen only when earthquakes interact with infrastructures and population. This study presents the details of the deterministic seismic hazard analysis (DSHA) of Delhi considering latest available information of seismic events and sources, within a distance of 500 km radius from the outermost boundaries of the city. Earthquake data catalog for the study region was developed by collecting seismic data from various agencies. Seismic event magnitudes were converted into a homogenized unified moment magnitude scale. A seismo-tectonic map for the study region was developed by superimposing the declustered earthquake event on the seismic source map of the region. The study area was divided into grids of size 0.02°×0.02° and DSHA was performed using attenuation relationship available for the active tectonic region. Peak ground acceleration (PGA) values were evaluated for 84th percentile values at the center of each of the grid points. Land use (LU) map for the study region was also generated using Landsat8 data. Hazard contour map, ward-wise administrative map, and LU map for the year 2016 are presented in this paper to revisit the seismic risk prevailing in the region.

Dr. Maneesha V. Ramesh, Renjith Mohan, M. Nitin Kumar, Deepak Brahmanandan, C. Prakash, Lalith Prakash E., M. Ananth Kumar, and Ramkrishnan R., “Micro water distribution networks: A participatory method of sustainable water distribution in rural communities”, Global Humanitarian Technology Conference (GHTC), 2016. IEEE, pp. 797-804, 2016.[Abstract]


Water scarcity has been a major thrusting issue in rural India, warrantinga high demand to design and implement different water distribution networks for easy and efficient use of existing water sources. Both macro and micro level systems exist of which, macro level water distribution networks have higher capital and maintenance costs. This is due to its size and the remote beneficiaries to which it caters. This paper describes the design of one such water distribution system in two rural villages in India whose design considerations includes the local community needs, availability of labor, local resources, climate, cost, and time for implementation. This paper also compares the micro and macro water distribution network's impact on sustainability. Sustainability is defined in terms of water wastage, usage rate, source capacity, total network length, cost of deployment, source recharge, and the network leakage rate. The paper discusses the water distribution projectscompletedin a village in Orissa and in a village in Rajasthan (two states in India) where all households were given 24/7 access to clean and safe drinking water for more than a year. The paper also draws insights on the socio-economic impact of the project carried out in these two states.
