P-Delta Analysis

P-delta is a geometric non-linear effect that occurs in structures that are subjected to compressive loads and lateral displacement. Under the action of compressive...

New Textbook: Modelling, Analysis, and Design of Overhead Steel Tank Supports

This book has been written to address an area of structural design which is usually neglected by clients, architects, and home owners. During the...

Detailing of Columns to Eurocode 2

It is important to carry out proper detailing after design of reinforced concrete columns. The requirements for column detailing is outlined in clause 9.5...

Modelling and Analysis of Imperfections in Portal Frames

Equivalent horizontal forces (EHF) are not strictly actions, but are forces that are applied to a frame in combination with other actions to model...

Procedures in Setting out of Reinforced Concrete Columns

Columns are critical structural elements used in transmitting superstructure load to the substructure. As a result, their stability and structural resistance is of major...

Structural Design of Encased Steel Columns

Composite sections of concrete and steel have a lot of advantages especially in the structural performance and fire resistance of a building. For columns...

Flexural Buckling of Columns

When structural members are subjected to compressive forces, the members may fail before the compressive resistance (A.fy) is reached. This premature failure is usually...

Design of Axially Loaded Timber Columns to EC5

Eurocode 5 deals with the limit state design of timber structures. In this post, we are going to present an example on how we...

Concealing of PVC pipes in RC Columns

In modern building construction, PVC pipes (plumbing works) on the surface of buildings is not always very desirable. In a country like Nigeria, PVC...

Structural Design of Steel Fin Plate Connection

1.0 Introduction The fin plate connection is very popular in the construction industry due to its ease of erection, and the absence of shared bolts...

Thickness Design of Column Base Plate Using Prokon Software

Last year, I made a submission here on how to carry out the thickness design of column base plates. See post below; Thickness Design of Column...

How to Analyse Sub-frames For Column Design Moment

In our last post, I highlighted the different methods of loading sub-frames such as to obtain the maximum design moment on the columns (Follow...

In the construction of reinforced concrete structures, reinforcement bars must be tied together in order to hold them in place and to also facilitate...

Cost of Reinforcement Works in Nigeria

Installation of reinforcements is an important item of work in the construction of reinforced concrete structures. The cost of reinforcement works therefore significantly impacts...

Design of Shear Walls

Shear walls are structural members that provide additional lateral stiffness to a building by resisting shear, moment, and axial forces, which are produced due...

Technical Guide: Detailing and Arrangement of Beam Reinforcements on Site
