This paper aims at presenting the effects of short-term sustained load and temperature on time-dependent deformation of carbon fiber-reinforced polymer (CFRP) bonded to concrete and pull-off strength at room temperature after the sustained loading period. The approach involves experimental and numerical analysis. Single-lap shear specimens were used to evaluate temperature and short-term sustai...

As a vibration- free concrete, self- compacting concrete (SCC) can be easily used in the absence of consolidation, therefore; it is a good option for repairing and retrofitting concrete structures. The quality of repair layer is highly effective on a successful repair. Accordingly, in this study, factors affecting the quality of fiber-reinforced self-compacting concrete repair layer, including ...

We discuss theoretically the force F between two colloidal particles, each of them carrying one single strand DNA. The two strands are complementary only on a finite sequence of (`) consecutive base pairs. We define an adjustment length κ−1 (a few base pairs): in the adjustment regions near both ends of the paired region, the tension is still mainly on one single strand. But in the central part...

Composite hydraulic cylinders are used to reduce the weight of construction equipment such as aerial work platforms or excavators. The is compensated by manufacturing from Carbon Fiber Reinsforced Plastic (CFRP), but this expensive. Therefore, study investigated a hybrid cylinder, which combination CFRP and steel, considering both performance cost. conventional cylinder rods made can prevent fa...

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...

In steel fiber reinforced concrete, the interface is a very complex and weak structure. It because of layer between matrix that reinforcing toughening properties cannot be fully exerted. The bond performance core meso-mechanical concrete. To study its influence on mechanical three-phase finite element models pull-out are established based cohesive zone model unified phase-field theory by means ...
