If you use a good structural tool (steel shapes, weld symbols, ...) for making a quick sketches or comments in Bluebeam or Adobe please share the info.

I am thinking to by online access to AISC Manual (AISC offers 50% off $67.50/year). I would appreciate any feedback (pros and cons) from current users of online Manual.
Thank you,

The contractor has already installed top flange splice plate and web plate but he is asking to weld bottom splice plate because drilling those holes is a little difficult. I did not want to mix bolting and welding in connection so I recommended welding all splice plates and removing already...
Section J5.2 of the 2010 AISC Specification addresses filler plates in bolted connections. When a bolt that carries load passes through filler plates that are greater than 1/4" thick, the shear strength of the bolts shall be multiplied by factor 1-0.4(t-0.25) but not less than 0.85 which limits...
I have created combined section (Wide Flange w/ Channel) using Section Wizard and exported it to STAAD as general section. How does STAAD perform AISC check code for this section?

On tall pipe supports we typically use pipe columns with solid baseplate and grout. To eliminate the chance of any future corrosion the client wants us to use this detail (“stolen” from DOT) with open base plate, leveling nuts and no grout. What do you typically use?

Cooling tower concrete basin (base 56’x38’ with 4’ tall wall) has multiple leaks like these shown on the attached photos. The contractor is proposing SealBoss 1500 Water Stop Foam http://www.sealboss.com/1500water-stop-foam.pdf
I would appreciate any feedback if you used this product before...
I am analyzing beam with knife plate welded to web and top flange using quadrilateral plate elements (see attached screen shots). The most stressed element is on beam web just below knife plate subject to both axial compression and bending stresses (fa=Sx, fby=6My/t2). Question is how to...
I am designing T Pipe Support on 6" thick paving (load at the base: downward 1.00 kip and moment 7.50 kip-ft). How would you calculate a tributary area of paving to resist this load? Thank you very much.

Our Pipe Stress Engineer told us that Caesar does not currently have the ability to do Wind and Seismic loads per ASCE 7-10. However the Client Specs require ASCE 7-10. The Client thought we could manually input ASCE 7-10 wind and seismic design parameters into Caesar but our pipe stress...
I have posted the similar question in CAESAR II forum with only one response (http://www.eng-tips.com/viewthread.cfm?qid=378300). However I would like to hear the structural experts’ opinions on this subject. Our stress engineer provides max reactions at pipe supports for “default” load...
Dear Caesar Experts,
Our stress engineer gives me reactions at pipe supports and I design pipe supports for these reactions. I need reactions for the basic loads (pipe dead weight, pipe operating weight, temperature, pressure, and wind, …) and I would combine them. However he told me that Caesar...
I am evaluating existing spread footing built in 1973 for new horizontal vessel (boiler). Everything works but min reinforcement required for shrinkage and temperature. Per ACI318 Section 7.12. for steel Grade 40 (from 1973) it is As,min = 0.0020bh = 0.0020*20*12 = 0.48 in2. Reinforcement...
The client wants to add a 24” flare line on top of existing piperack built in 1969. The structural model of the whole piperack were developed and wind loading was applied per client’s current design criteria (ASCE 7-10, V=150mph, Risk Category III, Exposure “C”). The additional loading on the...
