PANDA2, a computer program for the minimum-weight design of elastic perfect and imperfect stiffened cylindrical panels and shells under multiple sets of combined loads, is used to obtain optimum designs of uniformly axially compressed elastic internal T-ring and external T-stringer stiffened cylindrical shells with initial imperfections in the form of the general buckling mode. The optimum desi...

An initial punching shear failure or column loss in a reinforced concrete flat-plate structure may lead to the dynamic load redistribution surrounding connections. The demand and capacity at these connections will determine if subsequent failures occur leading collapse of structure. Therefore, effect needs investigation order evaluate potential This paper analyzes previous experimental work as ...

This study will discuss the evaluation of tubing strength in Well X that using Electrical Submersible Pump as an artificial lifting method. The be carried out to determine risk failure production due erosional damage and loads on during operation Pump. Burst, collapse, tension main focus evaluating load by considering worst conditions may experienced operation. calculation is done Microsoft Exc...

framed in a cognitive approach to task-supported l2 vocabulary learning, the present study used a pedagogical approach to investigate the relative effectiveness of tasks with different involvement loads on the vocabulary knowledge of iranian efl learners. the goal was to investigate the way that the construct of involvement load is related to the input hypothesis (krashen, 1985) and the output ...
