Dear All CivilEA members
Before I have my own thread specially for my review on speadsheet/others materials in CivilEA, temporaryly I will add my new review in this thread.
My first plan is about review on seismic design - pushover stuff only, but if I know I will add also my review here.
Today I will give review about "14 story building with 5 underground stories"
I will not debate about the contents & comments in that thread, but I will give you other points of view about those topics
In building/structure design there many aspects to consider, just some of them :
1) aesthetics/architectural consideration, in very simple word : the good looking of the building
2) strength consideration, this aspect is all structural engineers deal with.
3) cost/economical efficiency
... & others
Specially for building with multistory basement [ underground-multistory ], I ever read a report about "cost efficiency analysis with case some buildings with various number of basements story"
It's too long if I must talk all of them here, but I will tell the summary of it.
Simply, a building with basement more than 2 story basement --> the cost become inefficient
Then for the case : "14 story building with 5 underground stories"
It will reached cost efficiency if change become : 17 story + 2 story basements
I remember accident many years ago in a hotel project with just 2 story basement in downtown of my city.
This accident occur because of careless in design-planning & construction process in construction process of basement
They dig the ground & because of lack of planning, occur "landslide" & burried workers ( until dead ) in this accident.
Just 2 story basement in my story above, can cause accident, just imagine 5 underground stories !!!
It really need extra planning specially when construction process, must consider "landslide" when dig the ground for underground stories.
And also cost-efficiency to do such building is an important aspect too
I hope my review useful for all of you
Thx
