A Simple Technique To Obtain The Response Of A Structure Considering Soil-Structure Interaction (Ssi), Smit Kamal

Manipal Journal of Science and Technology

In the conventional analysis of structures, the effect of soil-structure interaction (SSI) is generally neglected. Analysis of the structures without considering the effect of SSI may not be a realistic approach for all the cases particularly when structures are subjected to forces due to earthquakes. One of the limitations of SSI consideration in the analysis is due to the complexity involved in such analysis and this is the main reason for neglecting SSI in the analysis. In this paper, an alternative method for obtaining a structure response that is similar to a structure taking SSI is proposed. In this approach, …

Development Of Analytical Models For Photovoltaic Systems, Arjun M

Interdisciplinary Collection

One of the frequent circumstances in photovoltaic (PV) systems is partial shading, often characterized by multiple peaks in its characteristics. As a result, modelling and delivering peak power is strenuous. Analytical techniques are well-known effective instruments to overcome such challenges by establishing

correlations between variables with the help of non-linear implicit mathematical equations. With an aim to simplify these models, earlier research has focussed on formulating explicit equations by making assumptions/approximations, leading to less accurate results. With today’s fast processing computers, solving nonlinear equations is no longer a problem. Moreover, the application of analytical techniques has only been limited to …

Investigation On Enhancement Of Seismic Performance Of Unreinforced Masonry Structures, Susanta Banerjee Dr.

Technical Collection

Earthquake causes a huge loss of life and property compared to other natural disasters. Almost 75% of the casualties due to earthquake were caused due to the collapse of the building and the substantial portion was from the collapse of the unreinforced masonry (URM) buildings. However, masonry is still more popular than other construction materials due to its lower cost and availability of material, and construction of URM does not need any technical rigor. The extent of vulnerability in masonry structures is high due to its brittle nature of the failure. Primarily, URM building is designed to withstand vertical loads, …
