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 strengths indicated by the multiple anchor bolt tests were conservative when compared to the results obtained from the testing program.

It has also been determined that the AISC/LRFD tension stress limits for bearing type connections could be used for designing WSDOT anchor bolt connections with A /2 inch diameter bolts.

WisDOT Bridge Manual. Chapter 27 – Bearings. July The required design input for the design of an elastomeric bearing at the service limit state is dead load, live load plus dynamic load allowance, minimum vertical force due to permanent load, and design translation.

The required design input at the strength limit state is shear force. 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. Refer to Figure for design data such as masonry plate size, anchor bolt gage, and overall bearing height.

Steel Bridge Bearing Design and Detailing Guidelines Introduction The purpose of this guide is to present steel bridge bearing details that are cost effective, functional, and durable.

Three major types of bridge bearings are presented. Elastomeric bearings.

Anchor Bolts: Load bearing bale walls shall be anchored to the foundation by ½ inch diameter steel anchor bolts embedded at least 7 inches in the foundation at intervals of 6 feet or less.

A minimum of two anchor bolts per wall shall be provided, with one bolt located within 36 inches ofFile Size: KB. concrete box beams and slab units. Since its longitudinal expansion capacity is limited, the main function of this bearing is to take up any misalignment of the beams with the surface of the bridge seat.

The expansion bearing is provided with a hole through which a mm diameter anchor dowel is inserted and compressible material is injected. 2( kips/bolt) = kips and the bearing strength of 2( kips/bolt) = kips. The strength of the bolts at the outer bolt line is governed by the tearout strength at the edge for the 3∕8-in.

The experimental evidence presented in this investigation also shows that the ratio of ultimate bearing stress of large to small concrete blocks can approximately be scaled to 1/S1/4, where S is the scale factor.

A mathematical equation to calculate the ultimate bearing capacity in term of area of lateral steel reinforcement is by: of-Plane Loading Due to Concentrated Loads In addition to designing walls to resist the distributed concentrated loads, the bearing on the masonry must also be checked.

Bearing stresses are calculated using the bearing area, A br, which is equal to the smaller of the areas obtained from the following equations: = 2 1 1 br A AA A (1) A br =2A 1 File Size: KB. Anchor bolts must be located so that the nuts may be put on with the whole bearing (including sole plate) in place.

The specifications do not allow the Contractor to disassemble the bearing in order to put the nuts on the bolts. On expansion bearings, the dimension SA is File Size: KB.

Bearing stress effects are independent of the bolt type because the bearing stress acts on the connected plate not the bolt. A possible failure mode resulting from excessive bearing close to the edge of the connected element is shear tear-out as shown below (Figure 4).

This type of shear tear-out can also occur between two holes in the. Where bearing assemblies are required to support structural steel girders fabricated from atmospheric corrosion resisting steel, the use of similar material for bearing plates may be considered. Deck joints.

Embedment of Anchor Bolt/Dowel Clean each anchor bolt/dowel so that it is free of all rust, grease, oil, and other contaminants. Unless otherwise shown on the plans, the minimum anchor bolt/dowel embedment depth is such that the adhesive develops at least % of the anchor bolt/dowel yield load as determined by the Size: KB.

Two (2) total rows of anchor bolts are allowed, one row outside of each column flange. There must be an equal number of anchor bolts in each of the two (2) rows.

For cases with anchor bolt tension and base plate bearing, this program calculates the bending moment in the base plate at two locations.4/5(3).

Bridge Bearings Introduction. Bridge decks supported by piers are susceptible to damage due to vehicle movement and heat expansion. The primary function of Elastomeric Bearing Pads is to provide a connection to control the interactions of loading and movements between parts of a structure, usually between superstructure and substructure.

It is also the goal to reduce the amount of judgment decision that must be made after the contract is let and to limit the amount of cost overruns. 1.Keywords: bonded anchor, load bearing capacity, bond strength, experiment, tensile load, high performance concrete 1.

When bolt-down grates are specified in the contract, provide two holes in the frame that are vertically aligned with the grate slots. Tap each hole to accept a 5/8" × - 11 NC × 2" allen head cap screw.

Location of bolt-down holes varies among different manufacturers.
