csd72, a2mfk, Thank you. I offer you my sincere love and friendship. Your respective posting's have motivated me to seek harder for what it is that I am after. One thing to remember is that your respective comments are not those that I have come to expect from Engineer's. Perhaps there are...

Kindly let me know if there are any design guides or text books that show step-by-step designs for a single storey residential building i.e. including all details from the foundation to the roof. I am also seeking design guides or text books for single storey commercials structures in steel...

normm, The threaded bar is being drilled through after the concrete plinth is cast.

Please see attached file for a sketch. The steel saddle plate type base plate has been used due the limited 200 mm (8") width of the concrete grade beam. Due to the limited width we are unable to use a four-bolt anchoring pattern to fasten the column base plate to the concrete. A couple of thru...

Please see attached drawings and photo (multi-page PDF). Existing slab is 10" thick, rebar is #6, f'c = 3000 psi. Rebar pattern in this area seems to suggest that the slab is spanning mainly in the left to right direction. No special rebar is called up around the existing opening. Client wants...

Bridge EI, Proposal is to jack at bearing location, replace bearings, disable pins, make girders continuous at the hinges and then re-deck.

Forgot to mention...there are no seismic forces to be considered at this location.

Existing bridge has pin - hanger hinges at two locations. Due to their inherent weakness, the pin-hanger details are to be removed by making the girders continuous at the hinge locations. Furthermore, bearings adjacent to the hinge locations have to be changed from fixed to expansion to...

Long loads (such as a long I-girder) are transported in a fabrication shop using two overhead traveling cranes. The two cranes travel on the same runway system. Each of the cranes have different remote controls. One obvious safety requirement would be that the rate of speed of each crane be the...

The code is CAN/CSA A23.3. I think it is similar to ACI 318.

dik, can you please expand on "not much you can do without overcutting the notch and epoxying embedded top bars at the notch" Is this to essentially replace the top bars (to be cutoff) with new top bars but now located below the notch?

hokie66, now that is outside the box thinking. I was trying to think outside the box but to no avail...I appreciate your suggestion.

A sketch of the existing and proposed grade beam is attached. The grade beam has to be notched to allow for barrier free access into the building. The slab on grade inside the building will also be dropped by...

This is an existing grade beam. Sorry I did not state this in my original post.

There is a 10" x 24" deep concrete grade beam reinforced with 2-30M (#9) bars top and bottom and 10M (#4 - 0.16 sq. in) stirrups at 24" o.c. The grade beam is supported on concrete piles (piers) at 20'-0" on center. Total length of grade beam is 100'-0". The total factored uniformly distributed...
