In this paper, an attempt has been made to study the behavior of beam and arch bridges subjected to static uniformly distributed loads. The target audience of this research paper is Architecture students because they would like to visualize the structural concepts for better understanding with minimal calculation. For this reason, a static load test was conducted on three types of beam bridges and on three types of arch bridges. The performance of the arch bridge is studied by changing the type of beam, and the results are compared with the beam bridge. Based on the test results, it is found that the performance of glued beam bridges is recommended for less span than arch bridges.

The agricultural waste is disposed of either by burning it or throwing it in a landfill. In this an attempt is made to utilize the agricultural byproduct corn cob to develop a green concrete. This in turn will reduce the environmental pollution and reduce the greenhouse gas emission from conventional concrete. The used corn cob is crushed into powder and is added as additives with cement. Experiments were carried out on mortar cubes and concrete cubes with 0%, 1% and 2% of corn cob with respect to weight of the cement and studied its dry density, wet density, water absorption, compressive strength, slum value and air porosity. by using corn cob waste to make a concrete cube with different corn cob percentages. From the test results it is found that concrete with corn cob as additives of 2% with respect to weight of cement give high compressive strength and has less weight compared to conventional concrete. Corn cob is an agricultural byproduct and thereby it absorbs more water than conventional concrete, but still it increased the strength as it fills the voids between fine and coarse aggregate and is evident from its less air porosity value. It is highly recommended to use corn cob as additives in concrete but still it requires further test to use under tensile load.

The Covid 19 pandemic threaten the life of individuals and there was a lack of information in treatment, handling of patients and disposal of waste. The psychological and behavioral impact on Humans due to outbreak of Covid is studied and based on that a person-centered care center is suggested. The research methodology used are surveys, interviews among stake holders and design details of person-centered care center. Based on the surveys and interviews conducted during pandemic, it is found that 94% of the respondents prefer to use private vehicles with at least one member to ac-company them. People prefer to use 3 ply facemasks, followed by cotton masks and N95. Existing literature discusses the physical effects on the individual, but this paper focuses more on pros and cons on human life during the pandemic and lock down period. Based on the study, care center with facilities to treat patients with different levels of infections and counselling center for the persons suffered from Covid and other infectious diseases to overcome their psycho-logical and behavior changes are recommended.
