Does anyone have experience in designing a RC retaining wall on a rock without a base? The base is omitted due to space constraints. Do we need to embed the stem into the rock to have a fixed end or is it just enough to pass dowels across the wall and rock without embedment? ANy other...
Hi,
I need a bit of advice on the selection of effective length for the compression capacity calculation of bottom chord of a truss(double inverted) when there is a mixture of tension and compression in this chord member. Please see the attached axial force diagram. What length should I use for...
Dear kootK
It's a 400x400x200(leg thickness) L Column with 300D pile
5 storey building with each storey has 4 corner L columns. I wonder how the no of storey matters
Tx all
@phemENG, to make the question simple, I put the no grade beam assumption.
@BAretired
What will be the best generalisable point to place the pile center to minimize eccentric moments, if the column is a corner column with equal span beams either side and it has some top moment due to...
Hi guy,
Simple question......One of my project, My building has an L shaped column. A single pile caps are proposed for the said column. I would like to know if I place the pile centre at the geometric centre of the L shape column(Which is at the re-entrant corner of L shape), Will it there any...
Hi Eng Tips
I am having a little confusion in curtailment of flexural reinforcement after stock length. Pls see attachment. Hope that my question can be understood by my figures and for easiness, I have put a list of notation. I just want to know whether the Y mm2 or Z mm2 amount of...
Thanks a lot kootK. You have understood it correctly. In addition will it possible to use ACI shear friction method for this scenario by treating axial force as a shear force?
Hi,
In a high rise building, A stepped column(offset column) is formed like shown in the attachment. The lower column section is reducing it's length by 33% to rise above a particular floor(at 6th floor of the 48 storey building). I would like to know whether any bursting effect will occur at...
Hi,
Please refer the attachment for my proposal for the said connection where this is a T shaped RC beam connection to be supported by Steel UC section(UC section need to be raised above to support upper floors). I appreciate comments on the connection in this regards. Thanks in...
Hi,
I am designing a 3m deep complex pile raft where the raft is supporting a complex arrangement of core walls + columns and the raft is supported by a pool of compression piles. So it is complex to use strut and tie method.
For the flexural design I have designed using strips based on model...
Thanks SRE. So it will be sufficient to place all together 5 points i.e. at it's volumetric centre, and directly below and above it & directly in sides along the shorter axis of the pile cap. No points required along the longer axis to the sides of the pile cap??
Hi guys,
I am encountering a mass concrete pour for a rectangular pile-cap of sized 33 m(L)x8 m(W)x3.2m(D). A temperature monitoring system to be followed for the casting of this mass concrete element using thermocouples at different locations. Can anyone give any suggestions for best locations...
