okay, thanks for all respond.. i really appreciate it :)

Hello.. i recently deal with foundation of shunt reactor (type air insulated reactor) equipment. The requirement state that there is not allowed any metal in range 4540 mm any direction. If the shunt reactor equipment can not be elevated by something like column structure as vertical support...

Hi everyone, this is the first time i use plaxis to analyse MSE Wall.. if i look at the toolbar, the reinforcement only available "geogrid", and if i open the properties material of geogrid on plaxis, there is only elastic (i can only adjust value for EA, if needed) and elastoplastic (i can...

Hi everyone, this is the first time i use plaxis to analyse MSE Wall (Mechanically Stabilized Earth Wall).. if i look at the toolbar, the reinforcement only available "geogrid", and if i open the properties material of geogrid on plaxis, there is only elastic (i can only adjust value for EA...

yeah, Mechanically Stabilized Earth.. i had both MSEW 3.0 & Strand 7, only trial license..in my country, SAP2000 and Plaxis are more familiar than STrand7 and MSEW 3.0

Does anyone ever use MSEW 3.0? where should i find the tutorial/walktrough? Can Strand7 use to analysed MSE Structure?

Working stress = 2000 psf Allowable Bearing Pressure = 2.5 * 2000 psf = 5000 psf or 239.4 Kpa..is such a little value.. well, do insitu test (eg. SPT, CPT, DCP). I'd rather do DCP test to defined bearing capacity underlaying without losing much time..(Correlation DCP to Bearing Capacity topic...

the allowable bearing pressure divided with working bearing pressure, must have value more than 2.5..known as SF.. the more undefined soil underneath the structure, usually has bigger its SF.. But, it is important thing to ensure the settlement (cohessive has more settlement than granular)...

thanks fattad, with pleasure i'm gonna check the GRS-IBS.. if you don't mind, could you please give me the link?

hi Sybie99, After you get the spesification (mix design), you can do this thing : - Spread the select granular fill (as per spesification) upto 250mm thickness - spread the cement - mixed with shovel/trowel/hoe - add water as per specification (eg 4% depend on spesification) - compaction with...

thanks soil1999, i'll check on Texas department of Transportation

hokie66 (Structural), please take a look the attached photo..pedestal means short column, which it has anchor bolt inside... note that concrete already pass 28 days.. http://files.engineering.com/getfile.aspx?folder=87361be5-c6a7-476c-b861-3e9d81b2c47b&file=pedestal_rough_sketch.jpg

RFreund : my first thought the same as you, as per AASHTO LRFD, the uniform reinforcement length is commonly used. I have another case (calculate by other people), that the lower reinforcement length is longer than upper layer, say the lower layer about 13 meter, the middle layer 10 meter...

if you meet rebar with yield strength 400 Mpa or more, and want to do welding, you should read "AWS D1.4 structural welding code - reinforcing steel"..in my opinion, length of starter bar for column equals to 40*Diameter

what will you do if found pedestal with top concrete cover say about 120 mm (while the design state that concrete cover 50mm) ? This condition raise after do core drill to take a sample..

Thanks BigH...i'm sorry, the point is global stability and compound stability..actually, the day before yesterday, i have been able to analyse that... How about uniform reinforcement length? can i reduced it? because the requirement is less than and the available effective length (preliminary...

thanks worldofmud, could you please to tell me, the australian standard number? i'm trying search on a google..

i have a problem with manual analyse of MSE stability due to slope failure. The MSE wall has 11.75 m height with soil reinforcement using geogrid (vertical dist 50 cm) as attached sketch.. analyse using AASHTO LRFD with strength load combination (1.35 EV; 1.5 EH and 1.75 LS) also An abutment...

does anyone know / heard about DCP tool with a flat cone ? what codes, that support about this ?

Thanks GeoPaveTraffic, Yesterday, i try to DCP test (hammer 8kg, hammer drop 600mm, cone dia.16mm and 60 degree cone angle), here is the result : Blows Penetration (mm) 4 100 6 200 5 300 6 400 5 500 4 600 10 700 25 800 42 900 68 1000...
