In recent years, wind energy has become a potential source of low carbon energy. The shape of a building is a significant factor in aerodynamics, providing an opportunity for wind power control and wind energy proliferation. This research project aims to study the design of high-rise buildings and investigate how wind affects energy absorption by developing an aerodynamic optimization procedure (AOP) and using Computational Fluid Dynamics (CFD) in COMSOL Multiphysics. This study aimed to optimize the building shape for wind energy exploitation. Optimizing the building shape in the early stages of design enables the control of wind-induced loads and responses and reduces the energy demand in high-rise buildings, where resource consumption is higher than that in low-height buildings. This study used a three-dimensional CFD simulation of wind loading on tall buildings to optimize the building shape. This research will provide valuable insights for architects, engineers, and building developers to design and optimize high-rise buildings for wind energy exploitation, reduce the carbon footprint, and improve the energy efficiency of buildings.

Structural elements such as beams, slabs and columns may require strengthening during their service life period. A concrete structure may need strengthening for many reasons such as to increase live load capacity, to add reinforcement to a member that has been unsigned or wrongly constructed. The FRPs have various advantages like, high strength to weight ratio, corrosion resistance and ease of installation and flexibility in its use. FRP material which are available in the form of sheet are being used to strengthen a variety of RC elements to enhance the flexural, shear and axial load carrying capacity of these elements. The objective of this experiment is to strengthen the RC beams using fibres and FRP sheets in flexure. In this experimental program CFRP and GFRP sheets were applied to the bottom surface and sides of the concrete beam with different configuration and their performance in flexure were studied. In this experimental program eight RC beams of size 1500 x 150 x 200mm were casted with two 10mm dia. bars as tension zone, two 8mm dia. bars as compression zone and 8mm dia. bars @ 200mm c/c spacing as shear reinforcement. The experimental result shows that the flexural strength of FRP wrapped beams were increased in the range of 23.49% to 67.9% in comparison with the flexural strength of the control beam (unwrapped). The flexural strength of the beam wrapped with the single layer CFRP at the soffit and around the sides (for full depth of the beam) and beam wrapped with the single layer GFRP at the soffit and around the sides (for full depth of the beam) exhibits better performance compared with other FRP beams and increase in flexure was 67.9% in comparison with the capacity of the control beam.

In the metro rail system, Long Welded Rails (LWR) have been used for less maintenance, smooth & safe ride at higher speeds. The arrangement of connecting rail and deck system causes an interaction effect in force transfer. The study of this effect in the structure is Rail Structure Interaction (RSI) analysis. In this study, the behavior of double-decker integrated structure, rail stresses and relative deformation are studied due to the bending behavior of the deck, bearing articulation & support stiffness with the proposed geometrical arrangement of the bridge and applicable loading as per standards. The effect of RSI analysis and limitations of additional stresses are referred with the guidance of UIC standards & RDSO guidelines. The double-decker elevated viaduct structure is proposed with a first level highway deck carrying highway loading and second level metro system carrying metro loading. In highway bridge deck, the decks are proposed with four span continuous to avoid discomfort due to more number of expansion joints and thereby provide smooth riding for passengers. The effect of RSI is studied in this paper by considering the above complexity of two-level superstructure with a different type of superstructure at the metro level due to the track requirement like U girder deck system at each track, I girder deck system as a single deck for both the tracks at the cross over / pocket track locations and I girder deck system at highway level with deck continuity. A finite element analysis is performed using the analytical tool MIDAS CIVIL software to study the interaction mechanism for this double-decker bridge structure. For this study, rail and deck (unballasted) are linked with a multilinear elastic spring as recommended in UIC 774-3R and other boundary conditions as per IRS & IRC standards. This paper discusses the behavior of structure from the results of the rail stresses and forces to the substructure due to thermal and live load effects at both level Metro Rail system and Highway Road systems.

This research aims to conduct a laboratory study to clarify the behavior of creep in Loess soils with the change of moisture content and applied stress. Soil was brought from Joseh area (southwest of Homs city), and its main properties were determined, after that a series of tests (time dependent deformation) were carried out for the Loess soils within the unconfined compression test. The results showed that the change of moisture content and applied stress on sample have a significant effect on the properties of Creeping of Loess soils, and the deformations that occurred are instantaneous deformations at the moment of load application, and creep deformations that begin with the passage of time. Creep deformations can be divided into three stages: primary creep, stable creep, and accelerated creep. The deformations were evaluated using the Singh-Mitchell theory, and the results showed that the Singh-Mitchell theory fits well the description of deformations over time for Loess soils, where the relative error between the largest and smallest value did not exceed 15%.ABAQUS program was used to numerically describe the creep behavior of Loess soils using the Singh-Mitchell theory .The results showed that the Singh-Mitchell theory within the ABAQUS program gave more accurate values than the computational Singh-Mitchell theory, and the reason is that because of the program contains multiple parameters that describe well the properties of elasticity, plasticity and viscosity for any natural body.

Concrete is the most commonly used building material due to its high strength, moldability, weather-resistant, and fire resistance, among other benefits. In recent years, there has been a growth in the usage of Micro Silica fume. Through the Ore sand Bridge building, records show that Micro Silica was used in the concrete. These fabrics are not only environmentally sustainable, but they also have technological advantages on both new and hardened mortar products. Both goods are agricultural by-products, but their usage decreases the amount of primary raw materials removed from the earth. Latent hydraulic content is micro silica fume and fly ash. It has intrinsic cementation effects, which must be activated. Combining the powder with Portland cement is a popular way to achieve these results. Pozzolana is the name given to pulverized fly ash. These materials may not have intrinsic cementation properties, but a cementation substance is created when mixed with a high alkaline material.

Self-compacting Concrete is one of the new innovative types of concrete, and it is used widely in the construction of several industries. This type of concrete can be made by using different admixtures and their combinations. The main aim of the SCC is to improve the durability of the concrete structure and also improves the workability of the concrete structure. Nowadays construction of large structures, it isn’t easy to compact the reinforced concrete without voids. This can be overcome by using self-compacting concrete. This type of concrete does not require compaction. So, it is one of the significant advantages of the concrete structure and saves time and energy. This Review paper explains self-compacting concrete and its advantages and uses, and applications of SCC. This paper helps to an understanding about self-compacting concrete.

The sum of CO2 that has been released into the atmosphere is roughly equal to the amount of cement produced. Cement manufacturing now consumes many natural resources and cement substitute materials in the analysis of Micro Structural Properties of Ternary Blended Concrete. The mixed proportion in this analysis is made of M30 Concrete. The cement is substituted with a mixture of two materials in amounts ranging from 10% to 50%. For the mix of materials, Fly Ash is kept constant. The specimen is a 150mmx150mmx150mm cube, and the concrete is cast in a 150mmx300mm cylinder. The cast specimens are held for 28 days to cure. Compressive and split tensile strength tests are used to achieve the results. The combination at 10%, at 20%, at 20%, and 20% produced better strength results in all proportions from 10% to 50%. Besides, scanning electron microscopy techniques were used to understand better phase changes and the formation of microstructures to maturing the combination of materials at various percentages. SEM was used to evaluate the microstructure of the concrete for five different varieties, which helps with solid growth. With the highest compressive strength gained among all the mixes from 10% to 50% with combinations for M30 grade of concrete at 28 days, significant innovative information on particle shape and microstructure was observed. Via SEM study, a good correlation of this Microscopical quantitative knowledge and material properties is also presented.

Geopolymer Concrete is a new innovative type of concrete, and it is used widely in the construction industries. This type of concrete comes into place due to reduced cement content usage in the construction of structures. Already we are using cement as a binding material widely in the construction sector, but the problem is due to the cement content Co2 emissions are mainly produced and one more problem is greenhouse gases are increasing rapidly during the manufacturing of cement. Then after a lot of researchers, finally we got a geopolymer as a replacement for cement. By replacing cement content with geopolymer, we can reduce the cost of construction and reuse the structural materials. So, this type of concrete is different from standard conventional concrete. We can minimize Co2 and greenhouse gases’ problem in the atmosphere and make the structure an environmentally friendly solution. So, this type of concrete is very famous in the construction industry, and there are benefits also excellent. So, it can be used widely in construction sectors worldwide. This paper may help understand Geopolymer Concrete for everyone quickly. It gives a quick review of the Geopolymer Concrete.
