Incremental dynamic analysis and static pushover analysis of existing RC framed buildings using the seismostruct software
Civil Engineering structures are designed to withstand environmental forces like an earthquake, along with gravity loads. These forces are random and dynamic in nature. Therefore the response of the structure is also dynamic and that is what causes the unsafe and uncomfortable conditions. So, performance-based analysis of the structure is required which can be achieved by Incremental Dynamic Analysis (IDA) as well as static pushover analysis (SPA). But, the incremental dynamic analysis is quite accurate and actual response of the structure of the structure from the particularly considered earthquake can be obtained by this method. It involves performing a series of nonlinear dynamic analyses in which the intensity of the ground motion selected for the collapse investigation is incrementally increased until the global collapse capacity of the structure is reached. In the present work, incremental dynamic analysis of reinforced concrete G+6 and the G+11 building is carried out. IDA curves are developed with respect to peak ground acceleration. Performance stages of the buildings such as yielding and collapse are defined with respect to peak ground acceleration of the considered earthquake from the IDA curve. Building susceptibility that is whether the building can sustain the particularly considered earthquake or not is found out using IDA. Also, serviceability criterion for inter-story drift ratio from IS 1893:2002 is checked from the IDA. Static pushover analysis of both the G+6 and G+11 building is also carried out. From the static pushover analysis, the graph of base shear to top displacement is plotted. From the graph, the base shear capacity of the building is found out. The base shear capacity of both the buildings is also found out using IDA and capacity curve of base shear to top displacement from IDA is compared with that of SPA.

Safety analysis in construction worksite using fuzzy AHP and fuzzy TOPSIS
Safety on construction sites is a complex issue. A safety management system (SMS) aims to decrease the number of accidents, injuries, and health problems among workers at a workplace. Ensuring safe workplace conditions at construction sites depends on different factors, including safety rules, management commitment, safety training, and safe behaviour. The current research aims to establish a method for identifying and evaluating the factors that impact workplace safety conditions at construction sites. The fuzzy analytical hierarchy process (AHP) technique was used to determine and measure the qualitative factor weights affecting workplace safety to assist in the evaluation of multiple concurrent criteria. Hence, the fuzzy AHP technique was used to determine criterion weight. Alternatively, a fuzzy technique for Order Performance by Similarity to Ideal Solution (TOPSIS) model was used to evaluate the performance of companies and rank them according to their safety performance. Based on the results and findings of the presented approaches, four companies were ranked for their overall safety performance. The findings are encouraging and can be used in the construction industry to benchmark the performance of con¬struction companies for their application of safety rules and regulations. The approach also determines the leading companies in terms of best practices and provides information for government inspectors to investigate the priorities identified for inspection.

Experimental study of construction and demolition waste in flexible pavement
With the steep increase in the population, construction and demolition of buildings around the world have increased at the same pace which has led to the accumulation of C&D waste. Their disposal is one the major problems as the huge amount of land is required for landfill. In this research possible use of C&D wastes in semi-dense bitumen, macadam has been studied, so these C&D waste can be disposed of properly furthermore the natural aggregate which is depleting at very fast rate can be saved for the future generation. In this study test are conducted to check the feasibility of C&D waste in the asphalt pavement .various tests such a marshal stability test, tensile strength test is conducted to determine the optimum percentage of construction and demolition waste which can be used in semi-dense bitumen macadam. It also helps in saving the material for future. That can be used for bigger construction. The demolition waste with the different percentages as a coarse aggregate has been used in this research and the results have been compared with the conventional mixes. Over 90% of demolition wastes can be filled with the land fillings and due to its toxic nature it will affect the soil and make it useless. Marshal stability and indirect tensile strength tests have been performed which resulted in the increase in the durability and strength of payments.

IoT based smart energy meter
Energy meter reading is a tedious and an expensive affair. The meter reader has to go and take the reading manually to issue the bill, which will later be entered into the software to automate the billing and payment system. This paper proposes a new network communication system for energy meter reading by internet communication technology and software system along with the existing meters. An IoT modem will be integrated with electronic energy meter to read the usage of electricity and uploaded on server or website. Energy meter delivers the reading details and it is uploaded to the website instantly. This communication system is further useful for electricity regional/sub-regional office, who can monitor the power consumption, and they cut the power supply for any specific house, who had not paid the electric bill using the EB Office Login. Moreover, this power cut control system is done by using the same website which is used for monitoring. In this project each customer is differentiated using address or ID, this ID is used for identification by the consumer and as well as my office to monitor the reading and payment details. The user can also monitor their usage from anywhere using the user login. An additional feature is provided to the user for controlling the power supply during in terms of emergency case.

Comparative study on CEC and CIC in composite buildings
Construction of steel building is booming in many parts of the world. The composite building consists of steel deck slab, steel beam, and composite column. In case of high rise composite buildings, Composite Encased Columns (CEC) or Composite Infilled Columns (CIC) are used. To determine the optimal column from CEC and CIC based on the seismic response and quantity of the material when used in a G+14 composite building is the objective of the study. Models of the composite building with infilled and encased columns are analyzed and designed using ETABs. Seismic analysis is done by Response spectrum method based on Indian code. Wind analysis is also carried out as per Indian Codes. The software results are analyzed for seismic behavior and the quantity of the material used for CEC and CIC are compared.

Sustainable soil stabilization using plastic waste
Soil stabilization is the process of improving the physical and engineering properties of the soil such as shear strength and bearing capacity, soil stabilization is also involving in decreasing the permeability and settlements as the soil is a loose unconsolidated material which is obtained by weathering of rocks and decomposition of organic matter. Which leads to the formation of different types of soils among different types of soils, the black cotton soil is the highly expansive soil which will be showing more swelling and shrinkage and settlement problems. In order to overcome this situation, the soil properties need to be improved by a process known as soil stabilization. This can be done by adding some external agents to it like coal, flyash, bagasse and plastic. Some experiments such as-as liquid limit, plastic limit, California bearing ratio (CBR) is conducted for the stabilized soil which will be showing the improved results in the engineering properties
