These models are then assessed with experimental data of FRP anchors and modified and recalibrated where appropriate. As a result, simple and rational pullout strength models for FRP anchors are proposed which can also be used in design. Finally, parametric studies are undertaken and the influence...
The anchors injected in mortar joints are shown to have much greater pull-out capacity than that found for anchors in bricks. Passing from 90 to 160mm of embedment depth, a minimum increase by 40% of pull-out strength is observed. The most common failure modes are the sliding failure, ...
Parametric study of factors affecting the pull-out strength of steel rods bonded into precast concrete panels This paper deals with the effect of bond thickness, embedment length and type of epoxy adhesive formulation on the adhesion of steel anchors to concrete. T... A Çolak - 《...
Investigations were undertaken to develop pullout tests that could be carried out on finished structures. Three possible approaches considered were: pulling out of tapered anchors placed in drilled holes; pulling out of bolts set in hardened concrete using epoxy; and measuring the force required to ...
The objective of this study was to analyse the behaviour of prestress strand anchorages by bonding with an epoxy adhesive for structural strengthening use. Pull-out and push-in tests were carried out on 15.2 mm diameter prestress steel strands sealed in 18 mm diameter holes with several embedment...
Fig. 44reflects the effect of epoxy resin content on the pullout strength of the epoxy emulsified asphalt with two kinds ofcuring agents. The pullout strength of epoxy emulsified asphalt rises with the increased epoxy resin content. In terms of the curing agents,curing agentA is more effective...
1.The relation between bond and slip of CFRP tendons and concrete structure were investigated and the bond destruction mechanism was analized by pull-out test.通过拔出试验,研究了碳纤维筋与混凝土结构的粘结与滑移关系,分析了粘结破坏的机理。 2.In this paper,the bond strength between high-strength li...
This study describes comparisons of the corrosion performance and pullout strength of black, hot dip galvanized and fusion bonded epoxy coated steel reinfo... S. Yeomans - "SP-126: Durability of Concrete: Second International Conference, Montreal, Canada 1991" 被引量: 21发表: 1991年 ...
Therefore, the local characteristics of the rock, such as roughness and induced fractures, are signi?cant factors in the anchor strength. To obtain realistic strength values, the test holes should be drilled using the same methods as the construction rock bolt holes. 5.4 Rocks with signi?cant ...
a 2D numerical model of the pull-out test is presented in order to study the impact of corrosion on the bond strength. Several parameters are investigated: the embedment depth, the rebar’s diameter, and the width of the concrete cover. The model reproduces the slip of the rebar and the...
