Thank you for your help. But I am afraid that the 2-branched column is not pinned for foundation. Each of branch tranfers axial load only, but the pair of axial load induce moment for foundation. The system is good only if two columns have a distance from each other to sit in 2 isolated...
Hi all!
I am designing an industrial building with bridge crane rated capacity 15 Ton. Because of poor soil in the site I try to design frame support pinned.
The broblem is lateral deflection due to wind load is very hight. But in our building code there is no deflection limit for steel frame...
Thank you all for your helpful advices.
I have checked the design and the result is:
settlement is about 8cm (high but ecceptable in our building code). I also tried N_value=8 would give OK result.
About seismic load I cannot insist the designer to
consider because I have no strong argument. In...
It is easier for me if I was the designer of this project. My company was hired for verifying design.
The site of SonLa hydropower plan as Focht3 mentioned is
in zone of frequent earquake (one for 10 years). But the site for my project have no earquake for hundreds years (or at least no...
The site investigation report (bore hole with disturbed samples) indicates that soil is uniform and homogeneous so I think plate load test is acceptable in this case. (SPT is better but to persuade the owner to re-investigate the site I need strong evidence as written in building...
This building is an airport station in central area of
Vietnam and I am checking the design.
This site have no surrounding building and very near sea.
As I know this is not a seismic hazardous zone but I
do not know whether to consider any activity in airport
as dynamic load or resonant...
Hi all!
We are designing a three-story building in a site
with 17m depth of fine grained loose sand. Ground water table
fluctuate by monsoon at 7<->3m below surface. We are considering
many methods of deep compaction and method of compaction/replacement
surface sand with medium grained sand...
Hi all!
I have a question about live load distribution according with ACI318 and ASCE7 (I am not familiar with the codes).
When designing R.C moment frame of 3 story building, should I check the structure for all combination of live load that may critical (checkerboard distribution of live load)?

I am from Vietnam and I am working at a project for building a new factory.
The designer of the project made foundation solution for this building site.
They improve soil using geogrid/geotextile, place 4m thk. compacted sandy fill on top.
For major foundations they...
Hello all.
I need to design spead foudation with width of 2.5m,
laying in fill of fine sand with depth of 4m, on top of 20m
depth of peat.
The soil is improved using geotextile.
My question is: What are typical characteristic of soils
for sand and peat should be used for calculation of bearing...
