Abstract

Even if living against the water is challenging, living with the rising water level is doable. The global average sea level is rising as a result of global warming. The land surface is being occupied by rising water levels. Several places of the globe are in danger of disappearing from the map, vanishing under water, due to rising sea levels. Society will have to adjust and possibly live in floating dwellings one day. Some countries are further along in their adaptation to the effects of global warming, particularly the rising sea level, than others, depending on their geographical location. In locations where the land is mostly covered by water, the sole option to survive the rising waters is floating house. A 96.6m. sq. long floating house with dimensions of 11.5mx8.4m is considered. This paper aims to construct a floating house and use Ansys software to analyse the structure.

Abstract

Now-a-days managing the traffic in major cities is a challenging task. One of the ways is to construct flyovers over intersections and to ensure smooth signal less traffic flow. The design philosophy has now become the design norm for most of the structural systems. To provide Reinforced Concrete Flyover Bridge is very essential in all major cities like Hyderabad, Chennai, and Mumbai etc. Our study is mainly focused on design and analysis of concrete bridge pier. The present study focuses on pier of an elevated bridge which is conventionally based on force based approach. The main focus of the present study is to perform an optimal design of a reinforced concrete pier which carries the deck of the flyover. The traffic flow is taken for 2 lane flyover on each side of the median. An Isogeometric topology optimization algorithm is used to determine the outline of the bridge pier. The bridge pier is then modeled in AutoCAD and imported to IDEA StatiCa® software. The reinforcement is calculated using Indian Standard (IS) code with all the necessary checks. The distribution of material within the given domain is determined. Shear strength, bending strength and crushing strength are calculated manually for checking strength compatibility. The static analysis and buckling analysis is performed using Idea Statica® software and the results are obtained.

Abstract

The shortfall of the force based method for the seismic design of Reinforced concrete (RC) structures has initiated the need of Performance based design. Force based method guarantees only strength criterion. For Performance Based Design, the design and evaluation criteria are expressed as performance objectives. The damages are articulated in terms of post yield inelastic deformation limits. Performance based design of 8 storey RC structure is carried out using pushover analysis. Initially seismic design is carried out as per IS code provisions, subsequent design iterations are made by accounting for cracked moment of Inertia and the iterations are concluded when structure possess sufficient amount of ductility.

Abstract

Laminated composites are increasingly being used in civil engineering structures. The light weight coupled with high strength has paved the way for using laminated composites in important structures such as bridges and roof shells. Isogeometric analysis using splines has been of immense interest to a structural engineer to model and analyse the structure in three dimensions. The present study is focused on using basis splines to perform topology optimisation of laminated composite thin shell structures. Three different shell have been considered elliptical, cylindrical and hyperbolic structures having simply supports on all four edges. Two different lamina have been considered 0/90/0/90, 45- 45/45/-45 for each type of simply supported shells. Inverse buckling formulation with the inverse of the buckling load is taken as the objective function to perform topology optimisation. Strength and stability criteria are included in the analysis. Deformed profile of laminates is presented here for each case of lamina using isogeometric analysis. The results of cubic basis spline based analysis are in good agreement with the results given in the literature obtained using finite element analysis.

Abstract

India is a developing country, and all its development schemes are not fully on the ground. In this scenario, the Indian Prime Minister launched the smart cities project in 2015. In this smart cities project, for creating a world-class city that possesses all facilities, the education sector, medical sector, hospitality sector, transportation sector, etc., are collaborating with the Indian government to bring change. Transport Telematics or Intelligent Transport Systems (ITS) are innovative tools based on the Information and Communications Technologies (ICT) applied in the transport sector. These tools enable authorities, operators and travellers to make more informed and 'intelligent' decisions. In addition, these tools improve transport management and increase efficiency and safety for public bodies while reducing energy consumption and environmental impacts, thus contributing to more sustainable transport.
