Structural Engineering

Our project aims at the study between RCC and steel framed structures. A G+2 commercial building is analyzed and designed in STAAD Pro. Time scheduling is done in Microsoft Project and also cost estimation is done. From these results both the structures are compared and the best suitable material is chosen.

In this project, we are designing analysing and developing an architectural model of a G+3 commercial building using BIM based software, through which we are aiming to portray the efficiency and effectiveness these software bring to the construction field.

In order to compete in the ever growing competent market it is very important for a structural engineer to save time. Complicated and highrise structures need very time taking and cumbersome calculations using conventional manual methods. So, the STAAD.Pro software provides us a fast, efficient, easy to use and accurate platform for analyzing and designing structures. The main aim of structural engineer is to design the structures for a safe technology in the computing field; the structural engineer can dare to tackle much more large and complex structure subjected to various type of loading condition. Earlier the loads acting on the structure are considered as static, but strictly speaking , with the exception of the self weight (dead load) no structure load is static one Now a day large number of application software’s are available in the civil engineering field. All these software’s are developed as the basis of advanced. The principle objective of this project is to analyse and design a multi-storeyed building[G +4 (3 dimensional frame)] using STAAD Pro. The design involves load calculations manually and analysing the whole structure by STAAD Pro. From model generation, analysis, and design to visualization and result verification, it is the professionals choice. Initially we started with the analysis of simple 2 dimensional frames and manually checked the accuracy of the software with our results. The results proved to be very accurate.

We analysed and designed a G+ 4 storey building initially for all possible load combinations [dead, live, wind and seismic loads]. STAAD.Pro has a very interactive user interface which allows the users to draw the frame and input the load values and dimensions.

In the present study, an analysis of concrete columns wrapped with composite materials is conducted and it is studied. This study is carried out by using the help of the software ANSYS 19.2. Different materials like steel, CFRP, BFRP, HFRP, AFRP and GFRP are taken into consideration for the study. A cylindrical specimen is modelled and material properties like Young’s modulus, Density, Poisson’s Ratio and Tensile strength of the wrapping materials are adopted in analyzing the composite concrete columns. Total deformation, Directional deformation and Equivalent stresses in the core and the shell of the composite column are obtained in the finite model analysis. The Stress variations, Ultimate load, Percentage reduction in deformation, Percentage Load Increment and also the behavioral study of different wrapping materials is observed. A cost analysis of various wrapping materials used in the composite column is conducted and the most suitable wrapping material based on the maximum allowable working load and the cost of the material is suggested.

The project focuses on design, analysis and comparison of multi storeyed buildings in seismic zones. So first,we have drafted a plan for the building. Then we have compared moment frame and shear wall for 10,20,30 and 40 storeyed buildings. So, after comparing the results shows that introduction of shear wall improves the performance of the buildings in seismic zone.Thus,making the structure better for the building in the seismic zone.

"The present work attempts to study the effectiveness of base isolation using lead rubber bearings (LRB) over conventional construction, using a case study of identical conventional and isolated building constructed in the most seismically active region in India (Zone 3). Base isolator is a device which decouples a super structure from its substructure resting on a shaking ground thus protecting structural and non-structural components. This project deals with design, modeling and analysis of G+9 rigid jointed plane symmetrical RCC frames for two cases. First case is fixed base and second case is base isolated (LRB). Building displacement and acceleration are compared for that both cases. For analysis ETABS software is used and for designing of isolator."

In our project we aim to propose a design for the extension of FISAT College Canteen. For that we prepared an architecture plan in AutoCAD. Modelled, Analysed and Designed the structure as both RCC and PEB in STAAD.Pro, taking into consideration the appropriate load combinations from Indian Standard codes. From the results obtained from STAAD.Pro we designed the structural elements i.e., Beams, Columns and Footings. After completion of design, construction time for both the structures are scheduled using MSP. After this we did a detailed comparison between these two structures and concluded that PEB is better choice in terms of larger span and lesser construction time. Thus we developed our model as PEB in REVIT.

Our project is the design of a bridge structure at aarangali in chalakudy using sap2000. The model is a concrete T- beam bridge with a span of 20m c/c distance with 6 deck sections having a total width of 10.5m loaded with 2 traffic lanes.

"The project includes the design and analysis of a Multi Level Car Parking system using Staad. Pro software. As we know that the number of vehicles in the streets are increasing rapidly and there isn't enough space for parking. It is high time to change the parking system in our country. The Multi Level Parking system utilizes more of the vertical space than the horizontal space. Cars are parked one above the other using robotic arms.

The study area was Aluva Central Junction. We visited the study area, took a survey on the vehicles parked on road sides and also surveyed a plot that is suitable for the implementation of such a system. A G+4 structure was drafted using AutoCAD and the different loads acting on the structure was found out in accordance to IS Codes. The platform used in the system was analysed using Ansys software and the result was applied onto Staad software. The analysis was completed followed by design of the structure.

Later, soil report of the study area was collected and studied. Based on the findings of the report a suitable pile foundation was designed using Staad.Foundation. We concluded the project by proposing a practical way to avoid the traffic congestions at the study area."

"Water tanks have been used since ages for the purpose of storage of water for various purposes in our society. It is an important component in the supply of water for commercial, industrial and domestic purposes. Hence, the construction and safety of these structures are important while considering the economy of society. The structural failure of a water tank is due to lack of proper knowledge about the behavior of staging of the tank upon action of various loads and its distribution and due to failure of geometrical selection of staging.

The Project is done to analyze the different staging conditions of a water tank and also to optimize the conventional type of staging of a water tank to get a new economical model. The water tank design is proposed in a water deficit area in west eleri, kaasargod. Seismic analysis is also carried out. Using STAAD Pro v8 analysis, different types of bracing systems, applied to the staging of elevated circular water tanks, are analyzed. Design of a circular water tank is done and also the permissible loads are applied to get a successful economic design. The modeling of different types of staging for the water tank from STAAD are checked and the failure conditions are analyzed. The optimization of the bracing system in staging is then carried out based on the economic point of view. Finally a suitable bracing system for the staging of a water tank with minimum economy that can sustain the possible loads is obtained"
