What is the appropriate response to a prospective client who wants a house designed on a pier foundation? The house is located somewhere in the northeast area of Pennsylvania.
I want to be able to explain what types of testing are required, what tests are optional(if any) and how to go about...
I am investigating the design of a 50' x 80' single story storage and/or work-shop type building that needs a foundation designed under it. Would a mat foundation thickened under the columns be the most appropriate? Or does the entire perimeter need to extend below the frost level?
Building...
I am looking for recommendations to upgrade my concrete text book to go with recent code updates and new design procedures. Are there any particular books that I should look to first?
Preferably, it would reflect the latest ACI code.
In our line of business we often specify a lot of bent plate fabrications, typically from 16gage cold-rolled steel sheet to 3/8" hot-rolled plate. Often, we take it for granted that the materials are "bendable" and that there will not be any adverse affects from the bending...
Is it an appropriate practice to use an E6011 electrode for welding A653 SQ Grade 50 steel (light gage studs and sheet) to structural steel? The steel types are job specific and could vary from A36 to A572 Grade 50 and beyond.
I have reviewed several AWS manuals and Welding Innovation...
Where can information be found regarding what types of bolts and nuts are weldable. And from that, can these welds be designed using the same parameters as those for "typical" steel members?
We want to use a threaded rod or bolt as a tension/compression member between two pieces of...
Does anyone know of any documented statements regarding the loading of a line weld with a transverse moment about its weak axis? I need to convince a fabricator that their details are not acceptable, but I don't want to argue this alone. A statement from a credible source would greatly support...
Can anyone elaborate on the effects of interstory drift on multi-story wall panels, i.e. "components and cladding"? I am involved in the design and fabrication of prefabricated wall panels (generally light gage steel frames with a variety of finishes, i.e. brick, EIFS, GFRC, etc.)...
What is the proper allowable stress design method for A325-X bolts for simple bending stresses? Are the bolts designed per ASD Chapter F, section F2 with Fy obtained from Table I-C in Part 4 Connections?
I am looking for commentary on the use of Fb = 0.75xFy from ASD 9th Ed. Equation F2-1. Can this be liberally used for shapes or portions of shapes that are considered compact as defined by the manual? I have been trained too much in the conservative use of .6xFy for most all of my bending...
Problem:
A structural engineer in our firm has been charged with designing a pole to support a light over a parking deck. Complicating the design is the desire for this pole to be designed from 6"x2" 1/8" thick steel. The pole is to mount to the side of the building and extend...
