Abstract: The objective of this study was to examine the elastic behavior of Douglas fir in the radial‐longitudinal plane. Parallel‐ and perpendicular‐to‐grain tensile test results were used to establish linear elastic behavior. ...

Abstract: This study investigated the tensile strength of Douglas-fir loaded at an angle to the grain. Strength was determined for grain angles of 15, 30, 45 and 60 degrees in the radial-longitudinal plane. Strength was found to ...

Abstract: An unexpected, but explainable, web buckle occurred during the field testing of the I-40 bridge over the Rio Grande in Albuquerque, N.M. The three-span continuous steel plate-girder bridge had a defect (physical cut) ...

Abstract: This paper presents the development of a new algorithm to identify dynamic properties of concrete by comparing simulated and experimental results of nonlinear ultrasound testing. Prismatic concrete specimens with different ...
