G'day!
Im chasing some properties for G250 and G500 reinforcing bars.
Query:
1.) Is there a difference in the strain for G250 (fy=250MPa) and G500 (Fy = 500MPa)? If so what are the values?
2.) How about the coefficient of thermal expansion?
Hoping anyone can assist or point me to the right...
G'day!
I have a geotechnical report on a very big area of land which contains the averaged CBR and Angle of internal friction plus the individual testing report for CPT, SPT, and even a trial fill testing.
I want to check the validity of the average and derive some specific values for an area...
G'day all!
somebody approached our office regarding a roll-over cage certification (on a forklift).
I have gone through AS2359.9 - High lift rider trucks - overhead guards - Specification and testing ( which is similar to ISO6055:1979).
The above code (australian)covers only the overhead...
G'day All!
Just would like to enquire if anyone can lead me to specifications or concepts on:
1.) Effects of soil inclination to foundation eg: soil is inclined and footing is inclined along it.
- doing some experiment with foundation and i have to incline a footing along the grade of the...
Good day!
I am looking into the forces involved in the design of a fire sprinkler pipeline foundation.
the diesel pump is pumping water from the sea to be used as a fire sprinkler water in a wharf. the pipe is inclined at around 40degrees and running around 26m up to the pump. the pump can...

I would like to have an info on MICROSTRAND...
I have searched it in the net but nothing came up so far. I only came upon Strand7.
Can anybody lead me to a website or info on this software?
thanks and more power.
I would like to ask for the formula of the coefficient of thermal expasnion for concrete and its parameters.
What is its effect in SOG cracking?
Thank you and more power.
We are currently approached to comment on cracks found on slab-on-grade and would like to ask for your idea on its causes and prevention. Cracks are found on corners especially near the stiffer retaining wall ( 250mm thk others are 150mm thk only )and also at the center of the slab. Building...
I'm looking into different options for my pre-cast piles.
One is by using pre-stressed concrete piles and the other is by conventional (using rebars only) reinforced concrete piles. Both piles are designed to maintain the required capacity.
Specifically, I would like to know:
a.)Advantages...
We are designing a retaining wall on the riverbank for a proposed four-storey building.
Our main concern is how much surcharge will the building impose on our retaining wall? Retaining wall height is 3.5m.
Any leads on how to compute surcharges in general?
thanks.
Good day to all!
Our company ( a construction firm ) has been approached to check on a rusted reinforcements of slab, beam and rebars under the Comfort rooms of a school building.
The building is quite old ( around 30 years ). The beams and slab has already cracked mainly due to the expansion...
I am currently looking into pre-casting a towercrane foundation so that this can be re-usable.
The towercrane manual usually specifies the foundation details depending on the soil bearing capacity and the tower height.

Here is a basic question that i would like to find an answer. I am searching for farther explaination on concrete covers.
1.) Minimum concrete cover for slab is 20mm while that of a beam is 40mm. Why the difference considering that they have the same exposures?
2.) Considering that the slab...
i am currently investigating if a 1600 kgs embroidery machine can be placed on the third level of a factory building.
note:
1)10 units will be distributed to an area of about 150 sq.m.
2) the embroidery machine vibrates when operated
3) the machines are operated continuously and...
Given that there is no available data, where is the best location to place the splice for column reinforcement?
I have received conflicting comments on this matter:
1.) Others would say that the location should be within the middle half of the column clear distance.
2.) Some would say that...
Can anyone lead tell me the limits for slab deflections for both one-way and two-way slabs?
Also, i would like to ask for the shape or formation of cracks at both top and bottom side for failure in slab design. ( both one-way and two-way)...

We usually design buidings for seismic requirements. A non-technical person just asked me what does the seismic zone and other criteria that we use mean in terms of RICHTER SCALE which is what most of us identify. Am now researching this, can does anybody here know?... any references?
