Types of Foundations in Building Construction

November 29, 2024November 29, 2024 Muyeen Mubarak

The foundation of a building is quite important as it supports the main structure and helps to make it stable and strong. Hence, choosing the right type of the foundation is very important so that a combination of site conditions, loading conditions, and design limitations are appropriately addressed. In this article, we explore the types of foundations in building construction, their uses, and recommendations for creating dependable structures. Foundation – An Overview A foundation is defined as the lowest part of a structure which is usually below ground level. Its…

How to Decide the Position of Columns in a Building Plan? | Structural Planning | Civil Tutor

November 22, 2024November 22, 2024 Muyeen Mubarak

After getting the architectural plan of a building, one of the most important tasks for a structural engineer is to determine the position and orientation of columns. This decision impacts the layout of beams, slabs, stairs, and the selection of footings. In this article, we will explore how to decide the position of columns in a building plan during structural planning. 1. Column Placement at Corners and Intersections One common practice is to place columns at or near the corners of a building, as well as at the intersections of…

Why do we prefer trapezoidal footings over pad footings?

May 24, 2023November 22, 2024 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?

December 29, 2022November 27, 2024 Muyeen Mubarak

Structural engineering, as it assists in the designing and building of structures like bridges, houses, and other extensive works falls under the area of construction. One important principle that is practiced by most of the people in this area is referred to as ‘strong columns and weak beams’. This principle means that portions of a structure where columns are situated should have greater strength and stiffness than the beams. The reason for this difference is that columns are predominant under axial compressive force and beams are mainly under bending. …

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…
