Hi, i came across R.C column which is reinfirced in two layers. Is this allowed? How the inner layer contriibutes? and if it's allowed could someone recommend some references or resources that discuss this. #See attached...
Hello, a 3m short column " column that extends from the foundation up to the suspended floor level" was designed as such, the client whiches to elevate the ground floor up higher "1.2 m " due various reasons. The problem with that is that one particular column fails. When designing theses...
Hi, i'm kindda new to ASCE7, i was wondering what are the limitations of ELF procedure, i.e when not to use it. In EC8, it is stated that only in case of vertical irregularity you shouldn't use the simplified lateral force method. Honestly, i'm not fully convinced with this, so i started looking...
Hello everyone, i have a question regarding wind loads. Is linear static method of analysis always used in wind analysis? If not, what are the limitations?.
This may sound silly, but how could i check that resonance is not a problem using Equivalent lateral force procedure, or the lateral force method in EC8
Hellow everyone, i'm trying to design a solid slab that rests on masonary walls. My question is about the design of the supporting beams. Knowing that these beams carry the slab and rests directly on the wall, how i could analyze and design such beams? Is it similar to beam on elastic...
Hellow engineers, i'm trying to model a two-story load bearing building using CSI ETABS, Solid slabs rests directly on masonary walls. To my understanding that beams are are rigidly connected to the slab. The masonary wall however should not be connected rigidly to the beam, as they are not able...

Beams do not carry any wall loads, the entitre building is carried on masonary walls so any the upper floor wall is supported on the lower floor wall

Hi, i'm trying to model a column that runs from the ground floor up to the 2nd floor without connecting to the 1st floor slab, that is length as one column should be double that of the other column and therfore its effective length is consequently larger than other coulmn. But, it seems to me...
Hello everyone, i'm trying to design R.C columns in a multi-story building, i've noticed that the demand/capacity ratio doesn't change when you change the column direction (rotate the column 90 degree so that the larger moment to be about the major axis. Could anyone explain why this happens.
Hello engineers i came across the concept of effective width in R.C beams, i found that the concept behind it is to account for shear lag and concequently the unevem stress distribution though i could not fully grasp how exactly this happens. Could anyone explain this more to me?
