Abstract When operating within the environments rich with sodium chloride, steel bars of reinforced concrete structures are often subject to corrosion caused by surrounding erosive materials, and associated rust expansion force due takes a critical role in determining durability relevant structures. By investigating course reinforcement theory elasticity, numerical model is established for mome...

Regional distance seismic moment tensor determinations and broadband waveforms of moment magnitude 4.6 to 4.9 earthquakes from a November 1997 Long Valley Caldera swarm, during an inflation episode, display evidence of anomalous seismic radiation characterized by non-double couple (NDC) moment tensors with significant volumetric components. Observed coseismic dilation suggests that hydrothermal...

First published March 8, 2002; 10.1152/japplphysiol.00696. 2001.—The series elastic stiffness (SES) of the human dorsiflexors was investigated in vivo with the fast controlled release method in 8 subjects. The maximum moment of...

The series elastic stiffness (SES) of the human dorsiflexors was investigated in vivo with the fast controlled release method in 8 subjects. The maximum moment of a voluntary contraction (66 +/- 17 Nm) was significantly higher than the maximum moment with electrical stimulation of tibialis anterior (34 +/- 16 Nm). At an ankle moment of 34 Nm produced with either voluntary or electrical stimulat...

The unexpected temperature drop during the concrete curing process could degrade properties at early age, and then decrease bond behaviour between reinforcing steel bars. To assess effect of low on structural safety, it is significantly important to investigate age under such extreme environmental conditions. In this study, pull-out tests were conducted early-age specimens with embedded deforme...

[1] Oceanic lithosphere undergoes permanent deformation during subduction once the stresses exceed the elastic limit. Departures from elastic behavior occur by brittle failure in the shallow lithosphere and by a combination of lowand high-temperature creep at greater depths. We combine laboratory-based rheological models with estimates of slab shape from earthquake hypocenters to quantify the b...

Induced earthquakes currently pose a significant hazard in the central United States, but there is considerable uncertainty about the severity of their ground motions. We measure stress drops of 39 moderate-magnitude induced and tectonic earthquakes in the central United States and eastern North America. Induced earthquakes, more than half of which are shallower than 5 km, show a comparable med...

Abstract The northern Red Sea in eastern Egypt is one of the world’s newest marine basins. a very active seismic region and poses significant hazard to nearest cities on coast. On June 16, 2020, moderate earthquake ( M L = 5.4), as published by Egyptian National Seismic Network (ENSN), occurred followed several aftershocks, ranging magnitude from 2.0 3.4. best-fitting double-couple movement obt...

buildings with wall or frame-wall systems are more effective against earthquake forces and sustain less damage than buildings which their lateral resistance is solely depends on frames. four reinforced concrete (rc) structural wall specimens were subjected to cyclic loading using finite elements method with abaqus software in order to study influence of diagonal web reinforcement. the research ...
