Abstract:

Rock bolting is one of the most common methods of rock reinforcement. To optimize bolt parameters for reasonably playing its properties under safe support condition, it’s a must to study the mechanical characteristics of roadway and bolt. This paper shows that anchor bolts at the top of the rise side has the maximum force, middle of the two sides minimal. Middle of two sides has the largest displacement, top and bottom smallest by using flac3d to simulate the force of special-shaped roadway under the support of anchor bolts, combined with field observance of anchor bolts force.

Abstract:

As an important method for connecting structural members, anchor bolts have been installed in many situations. Therefore, accurate evaluation of the pull-out strength of anchor bolts has always been an important issue, considering the complicated actual installation conditions and the problem of aging deterioration of the structural members. In general, the patterns of pull-out failure of anchor bolts can be classified into three types: adhesion failure, cone failure, and bolt break. However, it sometimes shows a mixed fracture pattern, and it is not always easy to predict the accurate pull-ou

In practical projects, GFRP anchor bolts are in complex geological conditions with corrosive factors such as acid, alkalis, salt and freeze-thaw circle. In corrosive conditions, the bonding strength of GFRP anchor bolts are in direct relation to safety of anchoring works. Based on comparative tests on bonding strength between GFRP anchor bolt and concrete, failure modes in pull-out tests of GFRP anchor bolt and concrete are mainly pull-out failure and splitting failure. Pull-out failure is a chemical and mechanical interlocking failure between GFRP anchor bolts and concrete cubes, which can ac

The pullout test of an anchor bolt is very important for the anchorage technology. Adopting enlarged bottom anchor bolts to wind turbine foundations can not only take advantage of the mechanical property of rock mass, but also have good security and economical efficiency. The finite element analysis software ANSYS is used in this paper to numerically analyze a single enlarged bottom anchor bolt under pullout loading, to research the performance and failure pattern of the anchor bolt.

Abstract:

Double-nut anchor bolt systems are used in the erection of traffic signal poles, high-mast luminaries, and other highway appurtenances. An absence of a tightening standard for such systems decreases the confidence in their performance under fatigue loading. Past research has shown that a tightening standard should include the development of preload in the anchor bolt sufficient to provide adequate resistance to fatigue failure. Preload should be measured by a turn-of-the-nut method. Laboratory progressive tightening tests were performed in order to monitor the stress ranges occurring in the b

During construction of dams, rock bolts are in general installed in the interface between concrete and rock as an extra safety measure against overturning failure. These bolts are however not allowed to be taken into consideration for the stability calculations of large dams. New standards and new design criterias have increased the requirements of the safety of the old dams, leading to a need for expensive rehabilitation and strengthening. It is possible that consideration of these bolts in stability calculations may lead to money being saved. In order to do so more information about the long

Abstract:

The mining industry is a major consumer of rock bolts in the United States. Due to the high humidity in the underground mining environment, the rock bolts corrode and loose their load bearing capacity which in turn reduces the life expectancy of the ground support and, thus, creates operational difficulties and number of safety concerns [1]. Research on rock anchor corrosion has not been adequately extensive in the past and the effects of several factors in the mine atmosphere and waters are not clearly understood. One of the probable reasons for this lack of research may be attributed to the

Abstract:

Shallowly embedded column base connections with unreinforced block out concrete are a common method of connecting steel columns to their foundation. There has been little research done to accurately quantify the effects of this block out concrete on the connection strength and rigidity, and therefore there is nothing to aid the practicing engineer in accounting for this in structural analysis. Due to this lack of understanding, engineers have typically ignored the effects of shallow block out concrete in their analysis, presumably leading to a conservative design.

This penetration is typically modeled with a single 6 degree of freedom (DOF) restraint at the plate in the pipe stress analysis. This approach can lead to overestimated loads on the welded plate and the mounting anchor bolts because no credit is taken for reaction on the embedded port
