A Database for Steel Braces with Respect to Inelastic Strength and Ductility Capacity
Steel braces are efficiently and economically used in seismic prone areas. Numerous researchers conducted physical tests of steel braces subjected to cyclic loading. Some past studies developed databases for less than 100 steel braces primarily based on both of strength and ductility at certain ductility levels. The paper presents the extraction of numeric data from images on past technical papers to examine the buckling strength, ultimate strength and fracture life of the steel braces compared to the past studies. The total number of steel brace specimens for the extraction was 377. Rectangular section, rectangular hollow structural section (HSS), I-shaped, and circular HSS were used for the section of the steel braces. The maximum compressive strength observed in the physical tests was compared to member requirements refer to 5 design provisions. The ratios of the ultimate tensile strength to yield strength were in the range of 0.7–1.6. A computational approach explicitly simulating fracture life of the steel braces was re-examined to extend the range of validity.
