The prismatic wedge shear test (priswest) is a relatively new test that enables the shear strength of gravels and crushed rock to be measured rapidly, using a portable frame and other simple devices. In testing which of the different methods of analysis for the wedge shear test is the more reliable for gravels, tests had previously been performed on 5-20 mm gravel with different spacing between the two halves of the priswest box; the method giving the more consistent results was proposed as the more reliable, based on the implicit assumption that as the spacing increased, the measured strength would remain constant. The present study was aimed at checking this assumption by investigating the effect on measured strength of the box spacing. No significant effect was observed.

Strength of sands in wedge shear, triaxial shear, and shear box tests Mirata, Tuerker; Erzin, Yusuf (ASTM International, 2007-03-01) Limited tests had indicated peak drained values of angle of internal friction (of gravelly sands measured in the cylindrical wedge shear test (cylwest) to be relatively closer to the (expected from plane strain tests than from triaxial tests. Such a difference was not obtained between the results of the prismatic wedge shear test (priswest) and the triaxial test on gravels and crushed rock. In this study, six sands with <3.35 mm particles were tested. It was seen that the main reason for the difference betw...
Seismic Performance of a Deficient Reinforced Concrete Test Frame with Infill Walls Kurt, Efe G.; Binici, Barış; Kurç, Özgür; Canbay, Erdem; Akpinar, Akpinar; Ozcebe, Guney (SAGE Publications, 2011-08-01) A two-story, three-bay RC frame with code incompliant seismic design and detailing is tested using continuous pseudodynamic test method for three scale levels of Duzce ground motion. The ground motion produced minimum, significant, and severe damage states on the test structure. Diagonal cracking of the infill wall, column damage in the form of cover spalling and rebar buckling, and complete disintegration of the infill wall were the important observed damage events for the three scale levels, respectively....
Creep behaviour investigation of a thin spray-on liner Güner, Doğukan; Öztürk, Hasan (Elsevier BV, 2018-08-01) Thin spray-on liner (TSL) is a fast-setting multi component polymeric material applied on a rock surface with a thickness of 2-5 mm. TSLs are primarily used as an areal support element in a support system that also incorporates rock bolts. Different laboratory and field tests were performed to understand the support performance of the TSL for underground design. The research described in this paper presents laboratory studies of the tensile creep behaviour of a cement based TSL for the first time in the lit...
Performance assessment of cement grout borehole plugs in basalt Akgün, Haluk (Elsevier BV, 1994-01-01) Flow tests have been conducted on expansive cement grout plugs with diameters of 160 mm and 200 mm, and length-to-diameter ratios of one, in boreholes in basalt blocks and in steel pipes. Two types of flow tests have been performed: pseudo-constant head tests and transient pulse tests. Hydration temperatures of cement grout plugs have been monitored in steel pipes with inside diameters ranging from 110 mm to 200 mm. During flow tests, basalt blocks have fractured, presumably due to water injection pressure,...
Effect of near-fault ground motion and damper characteristics on the seismic performance of chevron braced steel frames Dicleli, Murat (Wiley, 2007-06-01) This study is aimed at comparing the seismic performance of steel chevron braced frames (CBFs) with and without fluid viscous dampers (FVDs) as a function of the characteristics of the near-fault (NF) ground motion and FVD parameters. For this purpose, comparative nonlinear time history (NLTH) analyses of single and multiple storey CBFs with and without FVDs are conducted using NF ground motions with various velocity pulse periods scaled to have small, moderate and large intensities. Additionally, NLTH anal...
