Assessment of Pohang Earthquake-Induced Liquefaction at Youngil-Man Port Using the UBCSAND2 Model
Applied Sciences, 2020 The practical constitutive model UBCSAND2, which combines two-mobilized planes—a maximum shear stress plane and a horizontal plane within a framework of classical plasticity approach—is used to incorporate shear-induced effects in both loading and ...

New methodology for calculating damage variables evolution in Plastic Damage Model for RC structures [PDF]
, 2017 The behavior of reinforced concrete (RC) structures under severe demands, as strong ground motions, is highly complex; this is mainly due to joint operation of concrete and steel, with several coupled failure modes.

Cyclic simple shear tests on saturated sand in multi-directional loading
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1980 ABSTRACT Several series of multi-directional undrained simple shear tests were performed on saturated sand specimens, using a simple shear test device incorporating two pnumatic cyclic loaders in two mutually perpendicular horizontal directions.

Liquefaction Characteristics of Sands Based on Cyclic Direct Simple Shear Test [PDF]
Journal of the Korean Society of Hazard Mitigation, 2020 In this study, a series of cyclic direct simple shear tests were conducted on Pohang sand, Jumunjin sand, and Ottawa sand. The cyclic resistance ratio (CRR) was derived on the basis of the test results obtained. For verification of the effect of particle distribution on liquefaction resistance, the simplified method for evaluation of the possibility of

Experimental study on the cyclic resistance of a natural loess from Northern France [PDF]
, 2009 In order to analyze the instability phenomenon observed along the Northern High Speed Line of R\'eseau Ferr\'e de France (RFF), soil blocks were taken at a site near the railway, at four different depths (1.2, 2.2, 3.5 and 4.9 m).

Seismic retrofit of deficient exterior RC beam-column joints using steel plates and angles
Alexandria Engineering Journal, 2022 This paper proposes a simple and practical method for retrofitting deficient (non-seismic detailed) exterior beam-column joints based on fixing steel plates and angles around the joint with different configurations. Six half-scale exterior RC beam-column
