| 摘要： | This paper presents key findings of an experimental program performed to examine the rate-dependent behavior of weld material in transverse welded lap joints at elevated temperatures under steady-state thermal conditions. The data are intended to support the development of models of welded connections for structural-fire engineering applications. Two different loading rate scenarios (fast and slow) were incorporated in the experiments to evaluate the loading rate effect on the strength and deformation capacity of welded connection test specimens at ambient and elevated temperatures. Retention factors for the weld material under both slow and fast loading rates were computed and compared with those available in the literature. Results from this study indicate that the loading rate has a significant effect on the strength and deformation capacities of transverse welded lap joints for temperatures greater than 450 degrees C.
