Laboratory investigation of dowel bars’ misalignment using pull-out test

نویسندگان

چکیده

Joint lockup due to dowel misalignment significantly affects joint and concrete pavement performance by causing distresses. The current paper presents an experimental study assess the effectiveness of standard pull-out test in evaluation effect on Jointed Plain Concrete Pavement (JPCP). tests were conducted at two different ages ; 3 28 days. results showed that or individually pulling misaligned dowels cannot reflect realistic defect misalignment. It also vertical orientation bars during casting reduces load more distance from exposure surface. Another observation was for all specimens, increases with increase age.

Studies on the pull-out strength of ribbed bars in high-strength concrete

The transfer of forces from reinforcing bars to surrounding concrete in reinforced concrete (RC) is influenced by many parameters. Several efforts were made to understand the influence of bond on global behaviour of RC members. However, the information on bond strength of high strength concrete (HSC) is lacking. An attempt was made to study the influence of various parameters on bond such as ba...

A Remote Pointing Technique Using Pull-out

Reaching objects displayed on the opposite side of a large multi-touch tabletop with hands is difficult. This forces users to move around the tabletop. We present a remote pointing technique we call HandyPointing. This technique uses pull-out, a bimanual multi-touch gesture. The gesture allows users to both translate the cursor position and change control-display (C-D) ratio dynamically. We con...

An Investigation into the Pull-out Failure Mechanisms of Suction Caissons

This paper reports results from an investigation into the suction caissons failure mechanisms under vertical pull-out loads. An insight to the failure mechanisms of suction caissons paves the path for developing analytical solutions to their pull-out capacity. The numerical models of suction caissons have first been calibrated by and verified against several experimental data from other researc...
