+esign Calculation for #5torey d4elling ade /y asonrycross 4alls according to EC2.
The &ro*ect consists in the design of an individual d4elling/uilding 4ith underground% ground and one ;oor 7Ug.>G>1Fl.9%
&laced in ur/an environent 7&rovided 4ith electricity% &luing %
natural gases facilities and internet9.
Building ituation
The /uilding is situated at the the e8it of +orohoi city and is
connected to the se4age syste% to the gas syste% electric and
4ater syste and also to the internet. The ?one has a te&eratecontinental cliate 4ith the huidity lo4er in the 4inter and
greater in the suer.
The location of the construction is done on a relatively level
terrain% reduced slo&e5 under [email protected] geological surveys results
that the underground 4ater level is dee&er than the a8iu
foundation de&th. The area is on e8tra ur/an &lace.
