There are three types of analysis right -linear static -non-linear static analysis -linear dynamic Elastic analysis is considered as what??? Is there such thing as non linear dynamic??? Finite Element?? Response Spectrum? What category do they belong??? Working Stress Design and Ultimate...

why it is necessary to run a linear analysis before non linear one in ETABS??? THEIR ANSWER: You need to do a static analysis first and check equilibrium (loads vs reactions, etc) in order to validate your model. You cannot check equilibrium from non-linear analysis. 1. This is clear enough-...

Im working on an eccentric compound footing and am not sure whether i'm doing is right or wrong. I am in need of your guidance. What we have is an 4x1.2 eccentric compound footing and have been loaded with an ulitmate (0.2mx0.3m) column load of 60KN on the left and 53KN on the right. Considering...

Just to be clear... I am not designing, i'm investigating. Turns out you can use both??

I am currently working on investigating a truss using AISC code. I am confused whether what type of load combination to use. Whether to use ASD load combinations or LRFD load combinations or even both. WHAT TYPE OF COMBINATION SHALL I USE ANYONE????

what are your thoughts anyone? is it wise enough to be neglected?

in situations where the wall footing is on top of the spread footing, is it recommended that I neglect the effects of the wall footing in designing a spread footing? what are thoughts anyone? for two stories is it recommended?

very well said thx

I'm doing a retaining wall and am using a software for such project. I came across with an option that tells me whether to neglect seismic force due to stem self weight or not. Checking this options amplifies the resulting force and is indeed helpful for someone that desires a more conservative...

I want to know if Gala column reinforcement is reliable thx.

I'm looking for a cheap easy software that allows the analysis of concrete columns. The said program is easy, free to use and could easily be understood. Though it seems the software uses ACI-99, I believe that by changing default factors of 0.7 to 0.65 for pure axial limit could make it as if...

gala reinforcement for column design.

I found a R/C analysis and design software and would like to ask your thoughts regarding this? Anyone here who had tried this software? Kindly leave your comments below. thx.

I had just downloaded a program and am having hard time pasting loads to be used for my column investigation. The tedious process involves switching applications from time to time, copying loads at pasting it back to program. Each column is subjected to 5 load combinations and each load...

VERY WELL SAID THX SO MUCH

these are types of computer generated analysis used to determine reaction forces of beams, columns, etc. my question is how are they related and how do they differ?

what is the difference between elastic second-order analysis vs nonlinear second-order analysis?

ok thx

MY calculations are based from ACI By the way.
