Hi all. I have a reinforced concrete beam that has developed a significant crack on the bottom (almost 1/16").
With the size of the crack, the assumption is that the reinforcing steel in the bottom of the beam has yielded.
How would I calculate the remaining capacity of the beam? Is there a...
Hi all. I am doing a load rating of a concrete arch bridge in CANDE. Structure has a crack on the underside of one of the segments. Any ideas on how to model this in CANDE for the load rating? Thanks!
Hello. I was wondering if anyone can give me some feedback on Bentley OpenBridge Designer as a tool for bridge design. We are currently using RC Pier for substructures, CONSPAN for prestressed beams, MERLIN DASH for steel girders, and DESCUS for curved steel girders.
How do you think...
Hi all. I am trying to calculate haunch and beam seat elevations for a 2 span bridge composed of prestressed bulb T beams. The roadway is on a crest curve.
Now for a straight gradient, it should be calculated as follows, correct?
Net camber = the upward camber due to prestress force -...
Hello! I am working on the design of a two span bridge with integral abutments with a single row of piles and fixed pier. What are the typical horizontal loads that the integral abutment should be designed for? I have applied passive horizontal earth pressure due to backfill for the backwall...
Hi there. I am working on a bridge widening project. Structure is three simple spans, curved alignment with baseline radius of 1900', but the existing eight girders are straight steel girders with varying skew (approximately 45 degrees) with varying deck overhang. The two new girders will also...
Hi there. I am new to bridge design and would like some assistance. I am designing a multi column bridge pier with continuous footing supported on drilled shafts. I am using RC Pier and hand calculations in my design. I have designed the cap, columns, and footing and am moving on the drilled...
