Sometimes, after devastating events such as this dual M7.8 and M7.5 #earthquake tragedy in #Turkey and #Syria, people and the media tend to reflect and wonder whether eartquakes can be somehow predicted. Unfortunately, they can’t, at least with a resolution in time and space which could be used for prepardness…

concrete models which are confined and unconfined concrete models.
Now, in this post, I am sharing with you a couple of concrete models which are confined and unconfined concrete models. First of all why I am learning all these models? (you might be thinking) I am working on the performance-based seismic evaluation of RC structures. Having set an objective…
Important notes related to standard hook as per ACI318-19
1) Standard hook must satisfy minimum horizontal length (Ldh) , minimum vertical length (Lext) and bent diameter . (three basic requirements must be satisfied ) 2) Ldh can not be reduced by As,req/As,prov so full Ldh must be developed inside the support ( you may increase beam width or column…
Why most of engineers always are using diagonal reinforcement for coupling beam?
Why most of engineers always are using diagonal reinforcement for coupling beam ?!! ACI318 need to satisfy the coupling beam requirements just in chapter 18 for a special walls so coupling beam connects two special walls in high seismic regions . So if you have a beam connecting two ordinary…
When beam is failing in design then we have to check
When beam is failing in design then we have to check– 1)weather it is balcony beam or not.. if it is balcony beam then we can give it as ordinary design rather than ductile design…it will definitely pass 2)If it is not balcony beam then we go for torsional release…
