In reinforced concrete wall, the percentage of steel provided is greater than 0.4% and is designed similar to reinforced concrete columns. Slenderness ratio is equal to least of (l/t or h/t), where, l is effective length of wall, h is effective height of wall, t is thickness of wall If < 12, the wall is short and if > 12, the wall is slender.

ASTM C1018 is a standard test method for the flexural toughness and first crack strength of fiber-reinforced concrete. A 14x4x4 inch (350x100x100 mm) beam is loaded using third-point loading, while measuring net mid-span deflection. Testing is continued through crack initiation, up to a specified end-point deflection. Data collected after first-crack is used to …
