    The L bolts also greatly exceeded the minimum MPa (36 ksi) yield and MPa (58 ksi) ultimate strength requirements for ASTM A 36 steel and, for the most part, had slightly greater capacity than similar bolts tested in Phase 2. Anchor Prism Test Results When anchor bolts embedded in the masonry prisms were tested in tension, the boltsFile Size: KB. The literature search and analysis of existing headed stud and cast-in-place anchor bolt data was used to formulate an experimental program, conducted in the WJE structural laboratory. The program tested plate configurations in shear and 16 push-off type specimens. The tests were typically conducted in slabs measuring x m, or x.

    Again in Australia, a house with fiber cement exterior cladding and plasterboard interior finishes was tested to times its design lateral load capacity (Boughton and Reardon, ). The walls were restrained with tie rods to resist wind uplift loads, as required in Australia’s typhoon-prone regions. The roof and ceiling diaphragm was.

Title: Lateral Capacity of WSDOT Bearing Anchor Bolt Details Author: Rafik Y. Itani, Rachib Nakib, Duane L. Stone Subject: Anchor bolts, Bridge design, Bridges.

The objective of this research is to recommend a rational design method for bridge anchor bolt connections used by the Washington State Department of Transportation (WSDOT). An experimental investigation of the behavior of 3/4 inch diameter and /2 inch diameter. LATERAL CAPACITY OF WSDOT BEARING ANCHOR BOLT DETAILS.

FINAL REPORT. The objective of this research is to recommend a rational design method for bridge anchor bolt connections used by the Washington State Department of Transportation (WSDOT). An experimental investigation of the behavior of 3/4 inch diameter and /2 inch diameter, Author: R Itani, R Nakib, D S Stone.

The anchor bolts shall consist of A36 steel; have a minimum diameter of 1/2 inches and a length of 6 inches.

Cast the anchor bolts 4 inches into the concrete and set adjacent to the beam flange, one on each side. Place oversized washers or ¼-inch steel plates over the beam flange and onto the anchor bolt.

The lateral load resistance provided by each anchor bolt within the anchor bolt group was calculated on the basis of its lateral stiffness, which was defined as a function of the stand-off distance.

Close agreement with finite-element analysis solutions for various stand-off distance conditions was found.

anchors have become a foundation of choice for lateral load applications including slope stabilization, poles, towers and fences.

Design Guide Predicting Capacity Capacity is defined herein as the maximum load a foundation /soil system can support. The bearing capacity of a helical anchor varies depending on many factors such as soil. Anchor bolts subjected to combined axial tension and shear must also satisfy the following unity equation: av av bb B B +≤ Eqn.

10 The relationship between applied tension and shear loads versus allowable tension and shear loads is illustrated in Figure 5. STRENGTH DESIGN OF ANCHOR BOLTS pt The design provisions for anchor bolts using the File Size: KB.

Pull-Out Strength – Anchor Bolt in Concrete As a comparison, an anchor bolt set in a concrete foundation will typically crack up and out from the bottom of the bolt at a 45o angle in a cone shaped section. The force required to pull up this cone shaped section of concrete is the force requiredFile Size: KB.

The range of bolts now includes ordinary strength steels bolts such as gradesand and high strength steel bolts such as gradesand All connections and anchor bolts should be designed for a minimum lateral force of 19% of the dead load plus live load reactions at the support.

Anchor bolts should be anchored into the bridge seat to resist uplift. Figures through show alternate options to select for retrofit of bearings. The SSTB anchor bolt is designed for maximum performance as an anchor bolt for holdowns and Simpson Strong-Tie ® Strong-Wall ® shearwalls.

Extensive testing has been done to determine the design load capacity of the SSTB when installed in many common applications.

The Simpson Strong-Tie SSTB anchor bolts are code listed by ICC-ES under the. Hilti's mechanical anchor portfolio offers low capacity removable screws and sleeve anchors, medium-duty wedge anchors, and high capacity expansion and undercut anchors.

Mechanical anchors do not have the installation and in-use temperature restrictions of their adhesive anchor counterparts, and can be loaded immediately after installation.

A cast-in-place anchor bolt The simplest – and strongest – form of anchor bolt is cast-in-place, with its embedded end consisting of a standard hexagonal head bolt and washer, bend, or some sort of forged or welded flange (see also Stud welding).

This chapter aims to provide the knowledge of rock bolts and cable bolts. Rock bolts are either nonstressed or prestressed. Nonstressed anchors are also known as rock dowels.

Cable bolts are a group of wires used to create a cable. Cable bolts are used for high capacity applications. The most popular mechanical anchor system is expansion shell. Design of Anchorage to Concrete Using ACI & CSA-A Code Dongxiao Wu P.

The transverse load per anchor bolt is then: Using the bearing stress approximation from above, the required anchor bolt area resisting the transverse horizontal load can be calculated. A 1 is the product of the anchor bolt diameter and the length the anchor bolt is embedded into the concrete pedestal/beam seat.

Since we know the anchor bolt diameter, we can now solve for the required embedment length. Rockbolts and cables 5 mixed by this spinning action. Setting of the resin occurs within a few minutes (depending upon the specifications of the resin mix) and a very strong anchor is created.

This type of anchor will work in most rocks, including the weak shales and mudstones in which expansion shell anchors are not Size: 1MB. The BC Bridge Tie Anchors are made of high carbon, heat treated spring steel. They use standard 3/4” bridge deck bolts. An indentation in the fastening surface of the BC prevents the bolt from turning when being tightened from the top.
