Compressive strength as per American Codes. In case of American codes, compression strength is defined in terms of cylinder strength fc. Here compressive strength of concrete at 28 days curing is obtained from a standard cylindrical specimen 150mm diameter and 300mm high loaded longitudinally to failure under uniaxial compression loading.

Read MoreStrength of hardened concrete measured by the compression test. The compression strength of concrete is a measure of the concretes ability to resist loads which tend to compress it. The compressive strength is measured by crushing cylindrical concrete specimens in compression testing machine. The compressive strength of concrete is calculated by the failure load.

A strut under compression can therefore resist only a maximum force given by fy.

As designers gain experience using these calculations, they will more efficiently identify which load conditions are relevant to their particular application.

Read MoreIf youre worried about money, youre not alone. Money is a common source of stress for American adults. In fact, according to the American Psychological Association APA, 72 of adults report feeling stressed about money, whether its worrying about paying rent or feeling bogged down by debt. This is pretty significant given financial stress is linked to so many health issues.
