column position in a building plan

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?

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…

Strong column-weak beam concept

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.  …

Important concepts related to the design of columns (Every Civil Engineer must know)

Muyeen Mubarak

Important concepts related to the design of columns Columns play an important role in a building structure. Their main function is to carry the loads from the superstructure and finally transmit the load to the foundation. In this article I’m going to discuss some important concepts related to the design of RCC columns in which I will discuss the definition of a column as per the code, what are long columns and short columns, the Detailing of reinforcement for columns, and finally I will discuss the terms Nominal Cover, Clear…

Reinforcement lapping zone in column: The standard length of reinforcement bars is 12 meters, as we all know. If the span of a structural member, such as a beam or column, needs to be increased beyond the usual length of the reinforcement bar, we must also raise the length of steel bars by adding extra reinforcement bars. If the straight bars are added end to end, there is a risk of steel sliding out of concrete, which can be avoided by overlapping the bars. The goal of overlapping of reinforcement…
