How to Calculate Crackwidth Due to Bending According to EC2 (Download Excel Spreadsheet)

Cracking is normal in reinforced concrete structures subjected to bending, shear, twisting, axial tension, and restraint from movement. This is mainly due to the...

How to Analyse Retaining Walls for Trapezoidal Load

In the analysis of retaining walls subjected to earth pressure, it is very common to observe trapezoidal load distribution on the walls. Normally, earth...

Aspects of Modelling of Shear Walls

Shear walls are structural elements usually employed in tall buildings to assist in resisting lateral loads. Shear walls can be solid or pierced (coupled),...

Structural Design of Cantilever Slabs – Solved Example

Cantilever slabs are common features in buildings due to the need to have bigger spaces at upper floors. To achieve this, architects normally extend...

Crack Control of R.C. Slabs Using Simplified Rules (Eurocode 2)

The serviceability limit states covered by Eurocode 2 are; - Stress limitation (section 7.2) - crack control (section 7.3) and - deflection control (section 7.4)

Structural Design of Slabless (Sawtooth) Staircase

Slabless staircases (also called sawtooth staircases) offer aesthetically pleasing alternatives in buildings, and are often a source of wonder to those who do not...

Simple Proofs Why Shorter Spans Are More Critical in Slab Design

Introduction A slab is a structural member whose depth is considerably smaller than the lateral dimensions. They provide useful surfaces for supporting loads, and may...

An Introduction To Isogeometric Analysis (IGA)

1.0 Introduction Isogeometric Analysis (IGA) is a computational approach that integrates Finite Element Analysis (FEA) and Computer Aided Design (CAD). Isogeometric Analysis is developed for...
