Yes, the structural engineer is rarely acknowledged - the little bronze plate on the building only show the names of the client, architect and main contractor involved...
I guess we'll just have to start insisting on recognition from the beginning of a project. For instance, including a...
It'll be fine - just make sure the crank is max 1:10 and it's lap with the bottom bar is sufficient as per relevant code.
The moment will be taken down by the crank bar and transferred into the bottom bar if you create a slow bend for the crank and allow enough lap length.
As you said, both ways can be used. I prefer the lower bars being cranked into a position inside the upper bars (bottom crank according to your sketch).
The crank is then located in the beam/slab and not in the column. Also, it helps a bit in reducing the clashing with beam reinforcement...
Also sounds to me like a plate load test - used to determine the compressibility and sometimes the bearing capacity of soil.
I stand to be corrected but to find undrained shear strength of cohesive soils you can use the triaxial compression test.
Hi BA,
I think I reached a solution. Considering the base fixed, the moment working in on the base as result of the arch action (wanting to push the base out), counters the moment created by the eccentric axial load to some degree. And if I then play with the dimensions of the base to...
Thanks for your input guys.
Hokie. There is a retaining wall in between the columns, so I increased the retaining wall footing for a specific dimension - creating a T-shape base. Problem is, it's still very large - the top of the T will almost be continuous up to the next base (5.36m c/c...
The purpose of the foundation beam is to counter the horizontal forces generated in the arch beam wanting to push out the columns at the base.
I have also recommended the footings to be at the same level, but several things make it difficult, eg hard rock in-situ material; inside column level...
Hokie - a proper strap footing is a bit difficult, since the internal column is on another level due to existing building constraints. The internal column is also eccentric due to the adjacent building.
Csd - I have attached a sketch of the cross-section of the basement - please note that...
I am designing a column footing which must not project beyond the property line. The base is loaded with an eccentric column (1500x500mm) such that the edge of the column lines up with the edge of the base. To counter the large moment due to the eccentricity of the column, the base size...
I think it depends on how long you wait before the subsequent cast. If only a few hours elapse between successive placements, only a visual check is needed to be sure that all loose particles, dirt, and laitance are removed. The new concrete will be adequately bonded to the hardened green...
