EQGuys,
It is the preference of the client based on past experience. Material availability is not an issue but the client has not had success with cast-in-place concrete so they prefer everything precast. I believe their biggest reasoning for going in the direction of GFRP instead of steel for...
Hi All,
I am looking into the use of prestressed GFRP reinforcement for the design of bridge girders (box, NU or AASHTO type). Is anyone familiar with this? I am still determining the layout of the structure but most likely, it will be a single 100' span on 25 deg skew. Any example calculations...
I had looked into the GPR option but it was not entertained due to restriction of resources and time. In the end, I went with the shell analysis to show that resultant moment and shears from the permit vehicle were less than the design traffic load based on the controls I had suggested. Much...
I am planning my approach to do a structural evaluation for a 35' span rigid frame bridge on a 30 degree skew. The purpose is to obtain a permit for an oversized transport truck (265,000lbs). The issue is that the drawings are incomplete. Only the repair drawings are available, which do not...
The grade is actually 8%. Is that really impractical for an asphalt dump truck? My understanding is that the process can be done starting from the bottom of the slope but I did not see any specific limits on the grade for these trucks.
Thanks for sharing the information on BDM product! I have...
Hi All,
I am currently working on a bridge structure and there are a few concerns we have with respect to the deck waterproofing. Namely, the grade of the structure (almost 10% at the steepest section), temperature during construction of this phase (might be lower than 10 degrees Celsius) and...
