Although the ASTM A913 specification has been around for over 20 years, there has recently been a renewed interest in using ASTM A913 Quenched and Self-Tempered Structural Steel Shapes. Weight and cost savings are obtained by using the higher strengths of A913 versus conventional A992.  For building structures, the most significant advantage of this specification is for column and truss sections where the designer can realize a 10 to 20% weight saving by using the higher strength available in A913 Grade 65 as compared to the standard 50 ksi yield strength of A992.   …
