Check AREMA Manual for Railway Engineering, Chapter 15, Section 1.11.6. the bracing members used only for reducing the unbraced length of a member need not be designed for more than 2.5% of the force in the member.
Hello SWComposites,
I am very interested in the reference you mentioned: "Huth, H., Influence of Fastener Flexibility on the Prediction of Load Transfer and Fatigue Life for Multiple-Row Joints, ASTM STP 927, 1986, pp. 221-250". However, I don't have access to this article, is it possible...
Is this a highway project? If that is the case, you have to follow AASHTO Code. The minimum weld size allowed by AASHTO is 1/4" for plate thickness less than 3/4".
For slab supported by a steel cap from bottom, the tensile stress in slab is at top of slab, which means that "d" should measured from c.g. of top reinforcement in sab downward. If cap plate embedded in slab without chamfer, "d" should be measured to the top of cap plate; if cap plate is...
We specify 100 psf live load (impact included) for shielding design in our contract specifications; we also specify that any debris has to be removed within 24 hours.
Agree with Qshake, the key word is radial and the stationing at both abutments for all girders are the same, so for the same points (0, 1/4, 1/2 ...) all girders share a same stationing, which is of cause along the baseline.
Minimum pressure or uplift is the major concern of bearing design, this applies to both neoprene bearings and pot bearings. In the case of skewed bridges or curved bridges, a lot of efforts needed to deal with this issue.
In response to your question, My limited experience is this: neoprene...
