actually i have just tried it bass the base shear isn't affected; i guess if it was about forces, they would have written forces but not masses; i am not able to understand this translational mass what do they mean by it and an example of it.
Hi,
In the mass source in the Etabs software, there is the option in the mass source option to include lateral mass. In their documentation, CSI indicates that "assigned translational mass in the global X and Y and assigned rotational mass moment of inertias about the global Z axis are...
"The concrete punching shear capacity vRd (without shear reinforcement) will be determined from 2d*vrdc/a". This is what i am looking for. Can you tell me your reference please? It is somewhere in the EC or in the books you mentioned ? Many thanks again :))
Thanks again Hturkak. But i want to make sure that i dont need any punching shear reinforcement; i verified that along the column perimeter, the stresses are less than vrd,max. The thing is that the Eurocode should give additional capacity for sections located between the column perimeter and...
Hi,
I am designing a conic silo which has a foundation as per the attached. the dotted blue circles are the columns supporting the silo. The brown circles are the piles under the raft, having a thickness of 1200mm.
The design is conducted as per Eurocode 2.
When checking punching shear, and...
Oldest guy I wasn't clear in my original post. When I asked about the section capacity I meant the structural capacity and not the Geotechnical capacity.
Hello this is my first time I use a micropile. It has a diameter of 250mm. It will contain reinforcement consisting of 4 high deformed bars with some spiral reinforcement. My question is:
1. Is it mandatory to use grout and not concrete? Is it because I cant go with the tremie up to the bottom...
Hello, this is my first project in a Seismic Design Category D. I am checking the code requirements regarding the deformation compatibility (ASCE7-10 - section 12.12.5).
I have 2 interrogations where I would like to have your opinions:
1. Whenever I obtain the maximum story drift, should I...
Noted. Thank you.
Does the ASCE provide spectral parameters Ss and S1 based on different exceedance probabilities ? in other words, is there a document stating that for 475 years, the following parameters Ss and S1 apply and for 2475, other parameter values are applicable.
475 corresponds to 10% exceedance in 50 years and 2475 2% in 50 years.
How do you decide which one to use ?? I think eurocode is based on 475 return period and asce7-05 on 2475.
However back to the original question how do u take into account a higher design life span in terms of seismcity?
Hi
Any ideas how to extract the spectral parameters Ss and S1 for a structure having 100 years design working life ?
It seems that Ss and S1 provided in the asce7-10 are given for 50 years with 2% exceedance probability.
Thanks for the help
