Hi
I hope you are doing well.
I have obtained undrained shear strengths of 81KN/m2 on traixal test for a soil sample. The soil is stiff clay of high plasticity.
What is an easy way to obtain a value for young's modulus
Thanks
Hi All,
I hope you are doing well.
I have been instructed to design a new concrete ground floor for a renovation project. The ground conditions are London clay with a high volume change potential, please refer to image 1 for the borehole log. There is a 15m tall ash tree roughly 12m away from...
Hi All,
I hope you are doing well. Recently, I have ]been getting involved with trying to support a beam off a 100mm blockwork wall using resin anchors. The load on the beam is a modest 10KN. However, having looked at both the guides for Hilti and Fisher the allowable shear force force on a...
Hi,
As can be seen from the image above have a single pile loaded with service load of 30KN. It is restraint vertically via a ground beam. However, the only horizontal (left to right) restraint is somewhat lacking. Would it be possible to on a sort of cantilever action of the ground beams? I...
Hi,
In Principe how do you feel about supporting steel columns on brickwork walls. Seems unstable, would it be possible to place a column on wall if the wall is properly restrained as is the column. Personally I prefer to take my columns down to the ground but it sometimes feels easier just to...
Hi
I have recently been interested in the effects of "connecting" two beams together via a diaphragm (smaller beams or parallel flange channels). How would this effect lateral torsional buckling and deflection?. However,I am having a hard time finding any resources especially ones that refer...
Hi
1.) Euro-code seems to lack detail regarding issues such as deflection and rotation limits, now for a lintel supporting a brick wall what deflection limits are recommended. I normally used L/360 however I have heard other engineers suggest much more stringent requirements like L/500 or...
How do timber x braces compare to steel ones, Is there a minimum recommended width for the timber members. Do slender timber members have the capability to flex without cracking so that the assumption that only tension will be present in brace holds true.
Thanks
What is a good way to calculate Bending + Tension Interaction. I know one could use the standard interaction formula of
Bending Force/Bending Resistance + Tension Force/Tension Resistance < 1.0
But this does seem a tad bit conservative
I have been thinking about purchasing some steel connection software of late to speed up my design process. However, I recently spoke to an engineer who claimed that most software is not really that good, and all it takes is a few minutes and a few calculations to design a connection. I usually...
Where can I find out how to design a double notched beam in a fin plate connection against LTB, Would it be possible to just design the Web against LTB as a simple rectangular plate using the approach given in the following link...
Hi, so I know that bolted connections can be designed as semi-rigid, however would a designing a pre-loaded non slip bolted connection as fully rigid connection make sense or is there still a some element of flexibility in the connection. Thanks
Hmmm....Just been thinking, what kind of resistance would web stiffeners provide against warping. Say you could provide a post to restrain the beam from torsion, would adding web stiffeners allow the connection to be fully restrained against both torsion and warping. Thanks
Hi
If a beam rests on a wall consisting of two different strengths of brickwork, is it allowed to design the brickwork using the average strength.
Say the bearing length at 0.4 x the height of the wall under the pad-stone consists of 1.5m of brickwork of strength 1 N/mm2 and 1m of brickwork of...
Ok, lets say you have a rafter which is 3m long in plan and inclined at a 40 degree angle, how do you account for the incline. I normal adjust the loading, say 1KN/m by dividing by cos(40) so 1/(cos40) = 1.31 KN/m and then design it. However, would it be better to adjust the length instead of...
