All, I would like your opinion on a matter at hand. I work for a post-frame builder and we have a lot of porches attached to our buildings. What is your opinion on the wind load induced on the porch frames. Would it be components & cladding or MWFRS? Thank you for your help.
Hello, I am having a difficult time finding any type of design guidance on calculating the allowable longitudinal shear load for a top mounted embed plate into CMU (specifically a bond beam). The equations in Section 2.1.4.3.2 of ACI 530-08 are relevant for A) side/face mounted plates or B)...
I have a bit of a quandary. I am doing a roof framing evaluation for a client that wants to install solar panels. Currently I am determining the design the loads on the existing structure. The project is for a small college and the facility that I am looking at is large and therefore probably...
Does anyone know where I can find load tables for wood screws for fastening structural paneling to main member lumber? The NDS gives values for nails but not for wood screws.
Thank you.
Does anyone on here have experience with this type of single angle design (please see attachment)? My client is storming reams of aluminum coil stock on this storage rack and the angle serve two purposes, 1) to keep the reams from rolling and 2) to carry the load out to the support channels...
Looking for some experienced knowledge. Is there any literature, seminars, classes, or unwritten rules of thumb on how many nails to use in a plywood gusset that would compare to the amount of "spikes" or contact area of an original metal plate connected pre-fab truss?
Any help would be...
Just wanted to pick the brains of my fellow engineers out there. In your experience how have you gone about calculating shear/moment/deflection on a continuously supported member with a non-uniform (triangular) load. Obviously there is the easy answer of you can take the average and turn it...
I am currently working on a metal storage tank design for Glycol (density a little less than water), and I've seen some previous designs with tanks stiffenend with single angles. Is there any literature out there to figure out the "ring" tension and distribution coeffecients. I'm assuming that...
I wanted to see if anyone has any good literature on two-way slab design for point loads. I know that there is AASHTO for deck design using one axle or point loads, but these point loads a are smaller. Every example I've ever seen on two-way slab design is for uniformly distributed loads. Any...
I just wanted to pick some of the brilliant minds on here as to the best way to call out two-way slab reinforcement on drawings. I've seen hatching done with a schedule, I've seen it all done via details, and I've seen it done with plan notes. Any advice on the best way. I'm hoping there are...
Does anyone happen to know when they started implementing checking crane framing systems for lateral and longitudinal loading?
Thank you very much in advance for the help.
I was wondering if anyone has good verbiage to add to 03300 - "Cast-In-Place Concrete" spec. for prevention of thermal cracking due to Mass Concrete.
Any help would be greatly appreciated.
Thank you in advance.
Is there anyone out there that has a good cast-in-place conc. with metal shell pile specification out there that they would be willing to share? I was surprised to see that Masterspec doesn't have a section.
I am looking for a product that can seal cracks, like an epoxy injection, that is also waterproof, but here's the kicker..........I'm looking for something with a high viscosity.
Can anyone please point me in the right direction in AISC that gives the min. weld length at the ends of a built-up member?
Thank you in advance for the help.
Hello all. I am inquiring to see if anyone has any good literature/rules of thumb/design methods for check an angle leg for "tear out" from a lifting cable. I am designing a temporary lifting support frame and I am going to weld some 6" long anles on top of tubes. The vert. leg of the anlges...
I have a situation where I am connection aluminum handrail to a galvanized HSS tube, therefore a welded connection is the better option. However, once they make that weld to the tube and the galvanizing has burnt off wouldn't the connection be susceptible to galvanic action again? Would cold...
Does anyone know where I can find minimum bearing lengths for steel on steel? I looked in the AISC manual, but could not find anything. Thank you in advance.
I have a situation where we have trusses being fabricated in a different state (that doesn't recognize the difference between a SE and a PE) so when I received the calcs they are sealed by a PE in the state where they are fabricated. Where the project is located I am the SE of record. I am...
