I have a 2" plate that is sitting on (2) W10x15 beams. The plate is welded ( by the contractor) to the flanges of the W10x15 with a rectangular line weld 3/8" all around. Considering that the thickness of the W10x15 flange is 0.27", my understanding is that on one side the weld can be no more...
For an enclosed building, the wind uplift force on a roof is caused by difference of pressures above and below the roof membrane. The motion of the wind blowing over the roof creates a area of low pressure and the air under the roof membrane is at a higher pressure and so the wind tries to move...
Please see the wall footing snip attached. I have a 450 kip lateral force at the top of the wall which is about 23 ft high and 10 inches thick and 39ft long.
This is a non-load-bearing wall and the wall self is the only thing I have to resist overturning as well as sliding. The footing is...
I am required to design a condenser supporting steel structure for seismic loads. It will consists of 4 steel columns and tension only x bracing between the columns. There will be a network of beams connecting the columns at the top, thus forming a platform on which the condenser unit will be...
I am trying to design foundations for a building addition for an exiting building. The columns that are near the existing building experience high seismic loads as they form a part of the SFRS of the new building structure. The footings for these columns will have highly eccentric (in both...
I am designing an R=3 steel structure with the SDC = C. I would like to install tension-only x-bracing to resist the seismic and wind loads.
Per the process listed in AISC 341, for an R-3 SFRS, the brace is primarily checked for compression buckling as well as tension yielding. What is the...
I am designing the foundations for a large precast concrete structures that is Seismic Design Category D. I have received the lateral loads from the precast designers from a separate analysis of the superstructure considering fixed based approach. The lateral loads are large and in designing the...
I'm designing a Precast Concrete double T roof in Arkansas with SDC C. Does it require a concrete topping? as far I understand only SDC D and onwards need one.
Can someone could please recommend a foundation engineering book or any other text that details horizontal loads on shallow and deep foundations and includes worked examples?
I know how to calculate the wind and seismic loads and apply them to the footings. I don't know the mechanics of the...
