Abstract: Operation parameter influences on the behavior of the gaseous bubble in the lubricant for a groove textured journal bearing are studied under the consideration of the thermal effect of the bearing–shaft system. The influence ...

Abstract: A compilation of experimental results on the mechanical properties of concrete when exposed to rapid heating as in a fire are presented. Emphasis is placed on concretes with high original compressive strengths, that is, ...

Abstract: Effects of groove textures on the performances for gaseous bubbles in the lubricant used for a textured journal bearing is studied under the consideration of thermal effect of lubricant. The Reynolds, energy, and ...

Abstract: The effect of particle shape on the strength, dilatancy, and stress-dilatancy relationship was systematically investigated through a series of drained triaxial compression tests on sands mixed with angular and rounded glass ...

Abstract: An overview of fire damage sustained by the Pentagon structural elements in the September 11, 2001, terrorist attack is provided. The fire intensity in some compartments of the affected areas inside the Pentagon was ...

Abstract: The devastation in the September 11, 2001 terrorist attack on the Pentagon was reduced by the building’s resilient structural system. The continuity, redundancy, and energy-absorbing capacity embodied in this system should ...

Abstract: On September 11, 2001, the reinforced concrete structure of the Pentagon Building was able to resist, without collapse, the impact of a large commercial airliner despite the total loss of 26 columns and severe damage to ...

Abstract: On September 11, 2001, an airliner was intentionally crashed into the Pentagon. It struck at the first elevated slab on the west wall, and slid approximately

Abstract: The Pentagon was constructed between September 1941 and January 1943. A substantial renovation of the entire
