    (AIKTC, 2021-05) Nadaf, Firoz; Jahagirdar, Sayyeda Zara; Sawaid, Anjum (15CE37); Ansari, Shadab (15CE11); Shaikh, Faisal (15CE45); Shasudeen, Sajid (15CE35)
    Earthquakes are natural hazards under which clisasters are mainJy caused by damage or collapse of buildings and other man-made sn-uctures. Due to accommodation of vehicles and their movements at ground levels infill walls are generaUy avoided. which creates soft storey effect. It should be noled that 70 to 80 % of buildings of urban areas in India fall under the classification of soft storey. This soft storey is also called as Open ground storey or Weak storey. It is a typical feature in the modem multi-storey constructions. Such features are highJy undesirable in buildings built in ei micaJly active areas; this ha been verified in numerou experiences of strong shaking during the past earthquakes. The majority of building that failed during the Bhuj earthquake (200 I) and Gujarat earthquake were of the open ground storey type. The collapse mechanism of such type of building is predominantly due to the formation of soft-storey. As per Indian Standard JS 1893: 2002, the Columns and Beams of the open ground storey are lo be designed for 2.5 time the torey hears and moments calculated under eismic load of bare frame . This Multiplication Factor value however does not account for number of storeys, number of bay • type and number of infill walls present, etc, and hence it is independent of all of the above factors. The multiplication factor of 2.5 is not reaJistic for low rise buildings. This calls for an assessment and review of the code recommended multiplication factor for low ri e open ground storey builcling . Therefore, the objective of this tudy i defined as to check the applicability of the multiplication factor of 2.5. This study includes analysis of (G+7) RCC Framed building analysed u ing Seismic Coefficient Method (SCM) as per IS 1893: 2002. Io modelling the masonry in.fiJJ panels, Equivalent diagonal Strut method is used. This study basicaJJy includes Four models namely, Frame without masonary infill effect (Bare frame). Masonary lnfill frame, Frame with Tie-beam (Tie-beamed frame) and Frame with Bracing. (Braced frame) which are analy ed for Soil type I (Hard) and Soil type Ill (Soft) considering time period for seismic analysis as per Program calculated and as per Coda! provision. The response of columns in Open ground storey are discussed and conclusions are made in this study analysed on ETABS software.

    Dam breach analysis using HEC-RAS
    (AIKTC, 2021-05) Jahagirdar, Sayyeda Zara; Ahmed, Ammarah Ejaz (17CE01); Bhat, Aditya Subash (17CE12); Gazali, Sameer Imtiyaz (17CE18); Patil, Rushikesh Nathaji (18DCE10)
    This Thesis mainly provides an overview of the methods used to predict the breach outflow hydrographs with a detailed case study of hypothetical breach failure of dam ‘Kaliasot Dam’ using HEC-RAS software. The parameters describing a breach are typically taken to be the breach depth, width, side slope and breach formation time. The process of gathering data and preparing data and analysis of unsteady flow model in HEC-RAS, entry of dam breach parameters, performing the failure analysis and flood mapping in ARC-GIS is discussed. Here the maximum discharge, velocity, elevation and top width is obtained to find out the villages that are going to be affected at the downstream side of Kaliasot dam upto 30 km. It is easy to estimate flood and flood routing but it is very difficult to estimate the cost of maintenance and safety precautions for the given dam.

    Floating concrete using foaming agents
    (AIKTC, 2021-05) Jahagirdar, Sayyeda Zara; Pathan, Salman Abdul Razzak (17CE40); Khan, Shahnawaz Nafees (17CE27); Karel, Saif Ali Tayyab Ali (17CE47); Mirkar, Ateekulrehman Mubarak (18DCE08)
    The present day world is witnessing construction of very challenging and difficult civil engineering structures. Researchers all over the world are attempting to develop low density or lightweight concrete by using different admixtures in concrete up to certain proportions. The floating concrete is one of the concrete in which floats on water. Hence we know that the density of water is 1000 kg/cum. we supposed to be create a floating concrete it should have density of concrete lesser than density of water. This study deals with the development of Floating concrete by using lightweight aggregate (Pumice stone) and Aluminum powder as an air entraining agent. Floating concrete is made by introducing air or gas into concrete slurry, so that when the mix sets and hardens, uniform cellular structure is formed. We mix fine powder of Aluminum to the slurry and it reacts with the calcium hydroxide present in it thus producing hydrogen gas. This hydrogen gas when contained in the slurry mix gives the cellular structure and thus makes the concrete lighter than the conventional concrete. Pumice stone is a lightweight aggregate of low specific gravity. It is a highly porous material with a high water absorption percentage. In this we do not use the conventional aggregate and replace it by the pumice stone. Pumice is the specimen of highly Porous rocks having density approximately 500-600 Kg/m3. Pumice is produced when super-heated, highly pressurized rock is violently ejected from volcano. The unusual foamy configuration of pumice happens because of simultaneous rapid cooling & rapid depressurization. Pumice has an average porosity of 60-80% and initially floats on water.

    Smart irrigation using hydroponics in AIKTC
    (AIKTC, 2020-05) Maste, Junaid; Jahagirdar, Sayyeda Zara; Shaikh, Shahrukh (15CE46); Shaikh, Zeeshan (15CE52); Shaikh, Faisal (16CE43); Khan, Shaifali (17DCE55)
    Many of us think that all veggie gardens have to look alike, with rows and mounds of dirt, but vegetable gardening isn't limited to this anymore. In fact, many of the fresh fruits and vegetables you buy in the store are grown hydroponically, especially during the winter months or in colder climates. Hydroponics is a method of growing crops without soil. Plants are grown in rows or on trellises, just like in a traditional garden, but they have their roots in water rather than in dirt. Most of us confuse soil with nutrients. In fact, soil provides structure, not the actual food itself, for plant roots. The food comes from other materials mixed in the soil, such as compost, broken-down plant waste or fertilizers. Plants grown hydroponically can actually grow faster and healthier than plants in soil because they don't have to fight soil borne diseases; in addition, all the food and water they need are given directly to their roots around the clock. The objectives of our present study are to explain the meaning of hydroponics and describe some of its advantages, to describe how hydroponic system differs from traditional system, to identify advantages of hydroponics over soil based system, to identify basic requirements of hydroponically grown plants and to suggest optimum dosage of stabilizer for soil improvement levels. Keywords: hydroponics, smart irrigation, soil less irrigation.

    Urban issues and mitigation measures: Case of developed cities
    (AIKTC, 2021-05) Dasgupta, Rohan; Jahagirdar, Sayyeda Zara; Shaikh, Faez Ahmed Mushtaq Ahmed (18DCE04); Shaikh, Akbar Mohammed Saeed (17CE50); Yelukar, Ahmed Mohammed Kasim (17CE61); Nakade, Makhdoom Abdulaziz (18DCE09)
    URBAN POPULATION has been sharply growing since last several decades, and the rate of growth has been steadily increasing due to various factors such as economic reasons. In the future, not only the population in cities but also the number and size of cities are expected to grow. This profound growth in urbanization is imposing several serious problems on human and earth, such as pollution, deforestation and food scarcity. In our project, to learn and understand about such problems, we have selected a few cities from different parts of the world and assessed them on a wide spectrum of various parameters ranging from land use to transportation to architecture to environment and sustainability. Based on this research, we have selected a few urban problems, such as lack of open spaces, for further analysis. Then, we have studied about some cities which have successfully tackled these problems. Finally, we have presented a comparison of the selected cities highlighting the similarities and differences between them in a tabular format.
