Thanks for the answers. We are in SouthEast Asia. Likely not at my firm understands AWS and welding details, because we rare use built up members [primarily business in buildings]. The fabricator wants to use less CJP because it need to be checked using UT not as PJP [according to D1.1, he...

Hello, i am an new bridge design engineer. usually we design the welded wide flange in bridge truss and girder member as 100% capacity, and let the fabricator gave the member weld. Lately another fabricator asked about how it should be welded? And i was said that should be CJP [Complete Joint...

Hmm the design is back to the manual check then. It's very stressful for seismic large problem.

How to model sloped column in ETABS? not as brace.

Is there any books for discussing the cable element? Is there any recommended validation for cable element? NAFEMS?? Is there any good examples for modeling cables like sagging, how many mesh, and vibration modes? I am curious to the cable element, since likely every FEA has own variables on...

Please try the Eigen modes problem validation, especially from FEMAP shell and bending plate and compare with others.

Dear friends. I have checked some beam that needed for the truss structure. The structure needs the height of the beam 450mm. Since the truss wide enough, the beam is laying down, means the the minor axis is perpendicular to gravity axis. I've read the AISC LRFD 1999 and AISC LRFD 2005. I...

Nope, it's a frame of truss bridge, not a stringer

Effective with for composite? This is for truss bridge, not for composite bridge with slab. Effective width to Beam theory? I don't know. What i know is Timoshenko Beam theory consider the shear coefficient. It's that what you mean? I think it only effects on bendings which minor in this truss...

Yup, i usually check the allowable axial capacity just from unified formulas. When i check the deformation, i quite surprised.

Hi, i am designing a truss bridge. Is it possible to use fabricated steel section like I girder with 450mm deep [gross], 550mm width flange, 35mm thick web and 40mm thick flange? I know the boundary in AASHTO/AISC for limiting the minimum width of flange and thickness of flange and web due...

Hi, i am new here. I am designing deep pile foundation for building and bridge. 1. What allowable bearing capacity of deep pile is you more trust? a. based on Empirical Safety Factors methods :alpha methods Excel AASHTO , or Meyerhoff N-SPT excel, SPT97 / FB-DEEP N-SPT Allowable axial with...
