Dear Eng-Tips Members,
I would like to know if there is any limit on Maximum Volume of concrete that can be cast in one go?
Other than providing construction/Contraction/Control joints in hot weather, are there any other specification that limit maximum volume of concrete cast in one batch ...
Dear All,
I have designed the bridge between two building. Fixed at one end and roller at the other. The bridge at the roller end, rests on a concrete ledge. I have provided the expansion joint based on the formulation of ASCE for building separation. I have certain queries on it :
1- Is...
Dear all,
I am trying to design shearwalls through ETABS with temperature load applied over shell. At various location, spandral section fails in Shear due to temperature and piers (sometime in shear, mostly in flexure). (See Attached Image)
Certainly all the problem in Shearwalls are due to...
Dear Members,
I would like to have your feedback on the use of stiffness modifier. We generally use the value dictated by ACI committee as to model the cracked behavior, which are
Compression Member : Wall, Column, Pier = 0.7
Flexure Member : Beam, Spandrels = 0.35
Slab = 0.25
What if i want...
Dear All,
Do we design a Raft for One Way Shear, If Yes what is the criteria to check one way shear design of Raft/Mat foundation. ?
I am checking a Raft shear design with allowable shear stress in SAFE and doesn't seems to be reasonable. Most literature favors checking of shear forces rather...
Dear All,
I have a concern that I would like to address.
While exporting slab to SAFE for design. SAFE only account for column below with restrains but not column on the top. Though, it consider joint stiffness with col_stiff. I have went through few discussion that favor modeling column on...
Dear All,
I received a peer review about the modal analysis I conducted in a high rise building. It states the following :
"The preliminary mass participation factors indicate that mode 1 is predominantly translational in the transversal Y direction, mode 2 torsional and mode 3 translational...
