hello everyone, one question how can I prove that steel column embedded on 1' deep concrete will act a fixed support or something closed to a fixed support? Thanks for your help
The Lag screws lateral strength on chapter 11 of the NDS from a side plate to a main member say to be based on a penetration of 8D. Does anyone knows how the strength increases if a penetration depth of 16D is used instead.
Thanks
I have been reading about reduced beam section, and it says that it helps on the reduction of the need of continuity plates as well as doubler plates, but I dont understand the reason for this since having a reduced beam section increases the moment at the face of the column in comparison to...
Hello Everyone:
Are the continuity plates and doubler plate should be checked by the couple being produced by the Plastic Moment at the beam, or the moment at the face of the column due to the load (Shear and moment diagram).
I am confused, I thought I was the plastic moment, but I saw someone...
I am designing a grade beam foundation, and wanted to check its sliding resistance. I know that I have to considered friction and lateral earth pressure, but I am not sure to what surfaces of the grade beam I need to apply this lateral earth pressure to. Thanks
Hello everyone, I am currently designing a stair with just one stringer HSS shape, with steel plates as tread. Someone told me that when you design a tread, you need to apply the 100 psf and a concentrated load of 300 pounds. I am not sure where to apply the 300 lbs. If someone please could help...
I am designing a moment frame which has a grade beam joining the support and below two concrete pads at the support. How can I find the sliding resistance of the foundation.
Thanks
When designing a moment frame, Do we assume that a plastic hing will be created at the end of the column where the base plate is located? In other words, Should i design the base plate and foundation based on a plastic moment?
Hello guys, I am working on a soft story seismic retrofit of two story building apartment with a tuck under parking on the first level. The solution that I am using is steel moment frame at the carport. Should I design the shear, moment connections and the foundation based on the assumption of...
Hello guys. I am working on seismic retrofit of a soft story and using a steel moment frame as the solution. I am designing the foundation using a grade beam and pad footing at the support. I am trying to find the sliding resistance of the foundation and compare it to the base shear. I have...
Hello, My name is Daniel.
I am designing a base plate connected to a pad foundation with a grade beam on top of the pad footing. I have a axial load and moment transfering to the foundation. I found a page that says that when moments act at a foundation, it is normal to replace them by a...
