Why do we prefer trapezoidal footings over pad footings?

May 24, 2023May 25, 2023 Muyeen Mubarak

When constructing a building, it’s very crucial to ensure a foundation that is stable and can withstand the loads exerted upon it. Footings play an important role in transfering the weight of the structure to the ground. There are different types of footings available, each having its own set of advantages and applications. In this article, we will explore the reasons why trapezoidal footings are often preferred over pad footings in various construction projects. Definition and Purpose of Footings Footings are structural elements that are casted below ground level to…

The Math Behind Load Transfer Mechanisms in Framed Structures

February 14, 2023May 24, 2023 Muyeen Mubarak

What is a Framed Structure? A framed structure is a type of construction that is made up of various structural elements, such as slabs, beams, columns, and foundations, that work together to transfer and distribute loads throughout the building. Load Transfer Mechanism in Framed Structures: The load transfer mechanism in a framed structure refers to the way that loads are transmitted from one element to another and eventually to the ground. In a framed structure, loads are introduced into the structure through various means, such as gravity, wind, earthquakes, and…

What is Strong column weak beam concept?

Structural engineering is a field that involves the design and construction of structures such as buildings, bridges, and other large-scale projects. One important principle that is often used in this field is the concept of “strong columns and weak beams.” This concept suggests that the columns of a structure should be designed to be stronger and more rigid than the beams. This is because columns are typically subjected to compressive forces, which try to push them inward, while beams are subjected to bending and flexural stresses, which try to deform…

Difference between Load-Bearing structure and Framed structure

December 23, 2022December 23, 2022 Muyeen Mubarak

The two most common structural systems used in building construction are load-bearing structures and framed structures. In load-bearing structures the walls are designed to carry the weight of the building, transferring it directly to the earth. In contrast, a framed structure is a type of building design where the load is carried by an external frame or skeleton. The external frame of a framed structure is made up of columns and beams that are connected together to form a grid-like structure. The walls of a framed structure are typically non-load…
