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...
Thanks hokie66. No movement are allowed. But in sometimes I have seen a debonding to a short extent(say 4 inch) from the interface and thereafter anchorage is provided
Is it necessary to debond the shear friction reinforcement of the newly casting side of a construction joint of a tie beam???? Does is necessary to provide movement in the new cast??
thanks in advance
thanks all
@dik
Are you referring to a one couple of bent up bars over the column or just one couple of bottom bars anchored down to the column. What would be more effective??
@slickdeals
Yes. It is hard to apply Euro codes directly to this situation. Yes it is also true that the length of the...
