Hi,
I have to design a concrete slab within a chemical plant. The slab is supporting vessels. In case of a leakage or disaster the liquid flows via slope to a short channel and then into a collecting pit.
The liquid in the vessels is a solvent not attacking the concrete but that should not...
Dear Colleagues,
I have a problem by understanding the following:
The granular Subbase is supposed to be a lower quality material than the granular base.
If I refer to the "1993 AASHTO Guide for Design of Pavement Structures" to obtain the layer coefficients, I get the following:
a) Layer...
Hi,
the shear strength provided by concret Vc is given in clause 11.3.1.1. The version which I have says:
Vc=2*(sqrt(fc')/6*bw*d
in the internet I found:
Vc=sqrt(fc')/6*bw*d, but realted to the same code release.
Same appwears for the limit of Vs (clause 11.5.6.9):
Vs=8*sqrt(fc')*bw*d
and...
Dear colleagues,
We are facing a problem in understanding and applying the ACI 318M-02 for our project. It is the first project we do acc. ACI. It would be very nice if somebody can help us:
Problem: anchorage of reinforcement at joints / development of positive moment
12.11.1. (…) … such...
Hi together,
the structural calculation of a bore pile (dia 1m, l=56m, seismic UBC 2A) gives us a certain amount of flexural reinforcement. According ACI318 (and frankly speaking I don´t understand the code 100% regarding that issue) the pitch of the spiral reinforcement (or ties) is limited by...
Hi together,
the structural calculation of a bore pile (dia 1m, l=56m, UBC 2A) gives us a certain amount of flexural reinforcement. According ACI318 (and frankly speaking I don´t understand the code 100% regarding that issue) the pitch of the spiral reinforcement (or ties) is limited by 7cm...
Hallo together,
for our current project (very weak soil!) we use bore piles with a lenght of 56m ! The structural calculation gives us a bending moment up to a depth of 30m. If we consider our piles as columns we have to provide a minimum reinforcement for the whole lenght acc. ACI. Is that...
Hi all,
currently I am involved in a project in Egypt wich we design according american Codes and Standards. As I am not that familiar with the fire protection demands according american standards, I was searching for help in the web when I found by accident this references.
I would be very...
