Design calculation for a 2-Storey Dwelling made by Masonry Cross Walls According to EC6
Introduction
The structure is a rigid one made by masonry cross walls strengthened by concrete columns and girdles. It is assumed that the roof and floor plates are continuous in situ reinforced concrete construction. The roof system is a pitched support with 2 slopes and roofing. The stairs are made of concrete and the foundations are made as rigid continuous beams in situ concrete construction.
Technical Documentation
According to the project’s theme, the present documentation concerns a dwelling having the height regime of Partial Basement + Ground Floor + First Floor, designed for a family of 3.
The villa was built after the 1st of January 2011 and it is situated in Tecuci city, district of Galaţi, having the seismic degree of 8 (according to P100-92), the climate area B (STAS 10101/21-92), area of snow load C -150 , area of wind load B (STAS 10101/21-92), maximum frost depth of 0.90 m (STAS 6054/77). The access to utilities is assured.
The strength structure of the building is made of bearing walls of full brick masonry, slabs of reinforced concrete, and continuous rigid foundations of reinforced concrete. The roof system is a classical one, a pitched support with 2 slopes and tile covering. The exterior walls have an assembled structure, with an isolating layer attached to the exterior side of the bearing masonry wall.
The investment has the following technical indicators:
- Surface of the parcel (S_p)= 750
- Built Surface (S_c)= 106.31
- Developed surface (S_d) = 277.76
- Useful surface (S_u) = 205.07
- Livable surface (S_liv) = 56.94 3 rooms
- P.O.T. = 14.17 %
- C.U.T. = 0.37 %
The construction has a maximum length of 12.15 m and a maximum width of 8.75 m, with the regime B+2S. The maximum height is of 8.60 m at the roof and 5.73 m at the eaves.
The construction has the following divisions:
Basement:
- Fitness and Aerobic Room – 16.58 m^2
- Hall + Staircase – 4.13 m^2
- Locker Room – 16.39 m^2
First Floor:
- Living Room – 19.85 m^2
- Kitchen with Dining Area – 15.78 m^2
- Hall – 3.84 m^2
- Hall + Staircase – 11.87 m^2
- Toilet – 4.54 m^2
- Dressing Room – 7.55 m^2
- Garage – 16.58 m^2
Second Floor:
- Children’s Bedroom – 13.38 m^2
- Guests’ Bedroom – 16.58 m^2
- Hall + Staircase – 4.13 m^2
- Bathroom – 6.25 m^2
- Bathroom – 6.25 m^2
- Dressing Room – 5.69 m^2
- Master Bedroom – 26.98 m^2
- Balcony – 8.70 m^2
The building has a residential function, according to the requests of the beneficiary and has the strength structure as follows:
- bearing walls made of brick walls (25 cm thickness);
- thermal insulation consisting of waterproof polystyrene and extruded polystyrene with variable thicknesses that have been computed in this project;
- platforms made of reinforced concrete;
- the roof is of framing type, of wood, with covering of tiles of brown color;
- the access to the first floor is made through a staircase of reinforced concrete;
- the access to the attic is made through a hinged cover of 60x60 cm;
- the warm flooring is made of oak parquet;
- the cold flooring is made of ceramic plates.
