Engineers React to Large Span Cantilever Slab Construction

A structural engineer posted a picture of a large cantilever slab construction on LinkedIn, and so many reactions have followed the...

Cracking Due to Edge Restraint and Early Thermal Effects in Concrete

Crack width is calculated by multiplying the crack inducing strain by the crack spacing (i.e. the movement over a length equal...

Coefficient of Thermal Expansion of Concrete

Coefficient of thermal expansion is defined as the change in unit length per degree of temperature change. In a concrete element,...

Restraint and Restraint Factors of Concrete

If movement (expansion and/or contraction) is restricted within a young concrete element, tensile stresses will develop which will lead to cracking....

Cracking in Concrete

Eurocode recognises that cracking is normal in concrete subjected to bending, shear, torsion, and restraint from movement (clause 7.3.1 EN 1992...

Crack Width and Crack Spacing Calculation in Concrete

Cracking occurs in concrete when the restrained strain exceeds the tensile strain capacity of the concrete. In critical elements like water...

Minimum Area of Steel for Imposed Deformation Cracking

Minimum reinforcement is provided to ensure that yielding does not occur, and by so doing, cracking is adequately controlled in a...

Deep Learning can be used to Detect Cracks in Fire Damaged Structures

Researchers from Ewha Womans University, Seoul, South Korea, have proposed a machine learning technique for detecting surface cracks on fire damaged concrete....

Important checklists before casting concrete on site

Concreting or casting days are usually big days for site engineers. It is very typical to see engineers and project managers work...
