Prediction of building structure age using machine learning

Determining the service life of building structure is a critical step for the evaluation of maintenance of the building. If the service life of a building is known then proper maintenance and refurbishment steps can be taken. Previous studies focused only on physical obsolescence whereas new concept focused on other new six criteria. The objective of this paper is to use the entire six criteria for the evaluation of obsolescence for the prediction of the age of building a structure using machine learning. A prediction model for predicting age is developed by combining the six obsolescence criteria, absolute weights, diagnostic scores, and machine learning. As obsolescence is predicted using all six criteria, the manual calculation is reduced to provide more accuracy. This prediction model has built using python language, Django as a framework and PyCharm IDE. To make this prediction system more adaptable the website is created and hosted on webhost000.com by combining prediction model and UI of the website which displays the predicted age for respective diagnostic scores. Hence predicting age is useful for taking actions to prevent future degradation.

Experimental study: Alccofine as strength enhancer for geopolymer concrete

Concrete is the most consumptive material after water in the world because of its strength and durability. But the production of cement depends on natural resources and emits a huge amount of carbon dioxide into the atmosphere. For the sustainable environment and to reduce the global warming caused by the carbon dioxide emitted by the cement industry new substitutes which are eco-friendly is the need of the hour. Geopolymer concrete also is known as green concrete or cementless concrete produced by 100% replacement of cement with the waste product obtained from the industries. Geopolymer concrete uses fly ash, slag, and rice husk as a binder which is a substitute for conventional concrete. In present work, the different trail mixtures with variation in Alccofine were prepared to check the workability, compressive strength and permeability of Geopolymer concrete. Variation in content of Alccofine is done as 0%, 10%, 20%, 25% and 30%. As arccosine is an admixture which is micro-fine in its structure, so it may affect the fresh and hardened properties of Geopolymer concrete. In the study, results show that with increase in content of Alccofine up to 25% the significant increase in the compressive strength of concrete can be gained.

Potential of polythene usage in concrete

We as humans are living on the verge of declination because of the excess usage of plastics in our daily life. The construction world keeps on working in innovate ways in order to reduce the work load of the construction units. Plastics, a very important material that was being invented but this has to lead us to many problems like disposal, recycling, etc. the safe treatment of such thing or material is a great challenge to humans and its safe disposal is very challenging. Since this plastic led to a different type of pollution and these problems can be reduced by the usage of plastics in construction. Plastics have the potential to improve the properties of concrete like compressive strength, tensile strength, etc.

Experimental and analytical study on flexural behaviour of reinforced concrete hollow beams

This paper presents details of the studies carried out on flexural behavior of Hollow Core RC Beams with different core depths. As concrete is weak in tension, steel reinforcements are provided in this zone. The concrete is below the neutral axis act as a stress transfer medium between the compression and tension zone. However, in RC beams strength of concrete lying in and near the neutral axis is not fully utilized. So this un-utilized concrete is removed by replacing with any lightweight material. The experimental program consists of casting and testing of RC beams of size 100mm X200mmX2200mm with a hollow core in different diameter of PVC pipes like 12mm, 20mm, 30mm, 50mm from the top near Neutral axis. To study the flexural behavior, all beams are tested by two-point loading. The performance of Hollow Core Beams under flexure by using an analytical method (ANSYS) as well as Experimental method. It shows Ultimate cracking load is more for hollow sections when compared with Solid Beam.

Geometric design of highway using Civil 3D

It is essential to plan and design the road with safe, efficient, economic and easy for the movement of traffic and collect the details of different studies. Geometric design plays a major role in every road and it is weighty in the road alignment. AutoCAD Civil 3D is a software application used by civil engineers and professionals to plan and design the projects. This paper lavishes on a total geometric design of road using AutoCAD Civil 3D software. AutoCAD Civil 3D associate design and production drafting, greatly reducing the time it takes to implement design changes and assess multiple sets of circumstances. Although there are a number of factors influences on the design of highway, the suitable geometric design having the objective of giving optimum efficiency in traffic operation with contentment safety measures at a reasonable cost.

Review Paper

A review on “Study the performance of outrigger system under seismic loads”

High-rise structures in high seismic zones are subjected to earthquake forces, where the building performance is weakest in storey displacement and storey drift. Many types of research have adopted various techniques to improve the performance of high rise building. These techniques include the provision of core shear wall, bracing systems, dampers, etc. these techniques are able to reduce storey displacement to some extent, but the storey drift is the constraint was the performance of building weakens. This constraint makes the research work to adopt the technique of outrigger as an ancient technique used to reduce the vibration of the structure under the seismic shake. Hence, in this paper, a review of literature is studied to check the performance of the outriggers structural system in high rise building under seismic regions. The outrigger location and depth play an important role in the performance of the building. It is also observed that the outrigger structural system along with the core system reduces storey displacement up to some extent, but helps to reduce storey drift within the limit.
