Description

This is a recorded webinar from October 3rd, 2017.

There are many causes of volume change in concrete and masonry including changes in moisture and temperature, creep, and chemical reactions. Restraint can occur in the structure, e.g. due to lack of contraction joints or internally within the member, e.g. temperature gradient in a concrete pavement that results in the cooler surface being restrained by the warmer interior portion. Volume change that is restrained often leads to failure in the material or structure. Methods for calculating dimensional changes will be presented. Several examples of failures will be shown including cracking in parking garage columns, cracking in containment walls, collapse of masonry walls and fracture in the top of a swimming pool wall.
