Reduced web section beams in shear-yielding moment-resistant steel frames are used for energy dissipating of earthquakes. The finite element analysis indicates that failure mode of these beams are governed by the combination of shear force and flexural moment. Therefore the analysis of frames with reduced web section beams needs consideration of shear-flexural interaction in those sections. In ...

Numerical limit analyses have been used to evaluate the stability of the 17th Street Canal I-wall levee during Hurricane Katrina. The potential formation of a water-filled gap along the canal-side soil-wall interface at failure is included in both the lowerand upper-bound formulations. The analyses replicate published two-dimensional (2D) cross sections and soil properties developed in forensic...

Because of complex mechanical properties and deformation mechanism, gravel soil mixture is an important medium concern in the field geotechnical engineering. Based on continuous-discontinuous coupling algorithm formed by structure shell elements particle discrete element method (PFC3D), soft servo loading sample realized, typical triaxial compression test data are used to calibrate mesoscale pa...

Spot-welded advanced high-strength steel (AHSS) sheets are used to decrease car body weight and enhance crashworthiness simultaneously. Such welds susceptible hydrogen embrittlement, but research in this area is limited. We have evaluated the embrittlement properties of spot fabricated with AHSS clarified dependence diffusible content tensile rate on shear strength. However, performance must be...

Single solder interconnects were subjected to a series of combined tension–shear and compression–shear tests to determine their failure load. The failure envelope of these interconnects was obtained by plotting the normal component against the shear component of the failure load. The interconnect failure force map was found to be elliptical like the failure envelopes of many materials. The fail...

Due to frequent water level fluctuations and complex hydrochemical environments, rock slopes in reservoir areas progressively deteriorate become unstable. This study investigated the coupling effect of drying−wetting cycles acidic solutions on physical mechanical properties, strain field evolution, failure mode, micro-mechanism red sandstone using a series laboratory experiments (wave velocity ...

Abstract Based on five different constitutive models, the progressive failure process of deep hard rock was simulated, and plastic zone, shear strain increment high-value horizontal displacement, maximum principal stress distribution surrounding were obtained. The calculation results show that zone calculated by MCSS HBSS models is mainly concentrated in floor vault cavern, sidewall not damaged...

The effect of grain angle (GA) on shear strength of Douglasfi r has been evaluated. Shear block specimens with a GA varying from 0 to 90 ° was loaded in the shear plane, resulting in failure mode transitioning from parallel to grain shear to rolling shear. As expected, shear strength decreased as the GA increased from 0 ° to 90 ° . A root-mean-square equation was found to be suitable to predict...
