For safety purposes, I personally would replaced the monorail beam (I suppose its removable) with a new one that can take the load. KISS - Keep It Simple and Safe

For horizontal vessel, the consideration on the support is cantilever with concentrated load at top. Approximately we calculate period T (seconds) = 0.32sqrt(d) where d=PL^3/3EI (deflection in inches) P= Vertical Load (kips) E= Modulus of Elasticity (ksi) I= moment of Inertia (in^4) L= height...

Recently, a similar type of questions were raised in aisc.org, maybe you can try reading the response there. You can read also Chapter 9 of RCSC Design Guide (see the link below). It is not exactly the reference but can give you some guidelines. www.boltcouncil.org/2nd%20Edition%20Guide.pdf...

For our industrial and petrochemical structures I was involve, I have not seen a column splice without a splice plate on the web. It is an added assurance in splice connection. Maybe AISC wants to emphasize in the calculation of splice without consideration on the web splice plate so as to...

I'm not sure if this is the one your mentioning. Second paragraph of Section 1621.1, UBC 1997 Volume 2, page 2-7. Regards [colorface]

I think your problems can be best answered by a question also. Who’s holding the grout? I will use the values listed in bolts embedded in masonry, even if it is 1,000,000psi grout (just exaggerating). For your second question, my answer is “ perhaps they already consider a certain strength of...

Allow me to share my opinion. For structural point of view, if you want a rigid connection for rigid frame, its preferably best to connect the beam in the column flanges. For frames that do not required rigid connection (i.e., brace frame), its better to connect it in the column webs. For top...

To everybody, Pipe racks have transverse bents and looks like a portal frames with several level of beams to support the pipes. And bents are normally tied with longitudinal struts/beams (several level also) between column to column. Columns are supported by isolated footing (piled or unpiled)...

I am currently working on the offshore project (a floating production system) and also new to this type of project. I was assign to do a connection design of one of the module structure. In our go-by drawings on the connection of major pipe column and vertical pipe bracing seating on top of a...
