What is Wind and Earthquake analysis of structures?
Wind and earthquake analysis of structures is the process of determining the structural response of a building or other structure to wind and earthquake forces. This includes analyzing the forces that the structure will be subjected to and determining the design loads that the structure must be able to withstand. Wind and earthquake analysis also […]
Why should we provide structural members with end supports?
End supports, also known as end restraints, are provided for structural members to ensure that the member can transfer loads safely and effectively to the supporting structure. Without proper end supports, a structural member may experience excessive deflection or failure due to the loads it is subjected to. Providing end supports for structural members serves […]
What are the different types of steel used in reinforcements?
Let’s learn about the different types of steel used in reinforcements. The most common types of steel used in reinforcement are: Carbon Steel: Carbon steel is the most common type of steel used in reinforcement. It is made of iron and carbon and is available in various grades, such as ASTM A615 and ASTM A706. […]
What are the different shapes of reinforcements used for concreting?
Reinforcements, also known as rebar, are used in concrete construction to provide additional strength and support to the structure. The most common shapes of reinforcements used in concrete construction include: Round: Round reinforcements are the most common type of rebar used in construction. They are easy to bend and cut, and can be used in […]
This article describes the work sequence that a site engineer should follow during concrete placement/concreting. Work Sequence Flow chart for Concrete Work Prior arrangements for concreting Cleaning must be carried out to remove all debris such as binding wire, wood, and r/f bits, among other things. The site engineer will examine the availability of equipment/tools […]
The Fundamentals of Rebar Work
The reinforcement must be prefabricated with stirrups in place for easier on-site assembly. Reinforcing bars must be produced in accordance with the bar bending schedule and standard rebar arrangement drawings. Rebar cutting and bending The subcontractor is responsible for preparing the timetable for bar bending in accordance with the consultant’s approved “For Construction” drawings. Prior […]
How to Perform Hydrometer Analysis?
It is extremely difficult to separate soil particles with a sieve if the particle size is less than 0.075. As a result, a hydrometer is used to determine the particle size distribution of soil with particle sizes less than 0.075 mm. The size of the soil particles determines how quickly they settle from a suspension. […]
What are the Basic Soil Tests?
There are some basic soil tests that can be used to investigate the approximate engineering behavior of soils. The most commonly used basic soil tests are particle size analysis and the Atterberg limits. 1. Particle size analysis Particle size analysis attempts to estimate the relative proportions of the various grain sizes that make up a […]
What are the Atterberg Limits?
Let’s learn about Atterberg Limits. When fine-grained soils contain clay minerals, they can be remolded without crumbling in the presence of moisture. The adsorbed water surrounding the clay particles contributes to their cohesive nature. In the early twentieth century, a Swedish scientist named Atterberg created a method for describing the composition of fine-grained soils with […]
An Introduction to Arches
Natural arches are generally stable when it comes to the load distribution. It contributes to the reduction of bending moments in constructions with extensive spans. Forces acting on inverted cables are mainly compression, some shear forces, and bending moments due to rigidity. Evolution of arches Different types of arch bridges Corbel arch bridges Corbel arch […]
