Under a general case, the number of layers and the total height of the house should not exceed specified in Table 7.1.2 .
7.1.2 Storey layers and height should meet the following requirements :
Under a general case, the number of layers and the total height of the house should not exceed specified in Table 7.1.2 .
Note : The total height of a house refers to the height of the ground outside the main roof panel roof or eaves , semi- basement floor , counting from the basement room , full basement and semi-basement embedded solid good condition should allow counting from the outdoor ground ; on tape sloping roof attic wall should be considered to jian 1 / 2 height ;
2 interior height is greater than 0.6m, houses a total height increase should allow appropriate data in the table , but not more than 1m;
3 B of multistory masonry buildings should be allowed by the region fortification lookup , but should reduce the number of layers and the total height of the layer should be reduced 3m.
4 table does not include the small concrete block masonry buildings of reinforced concrete small hollow block masonry buildings ;
Two pairs of hospitals, school buildings and other less horizontal wall of multistory masonry buildings , with a total height should 3m, a corresponding reduction in the number of layers layer lower than specified in Table 7.1.2 ; layers of transverse wall a few multistory masonry buildings , should be further reduced level.
Note: The transverse wall means less greater than 4.20m in the same room floor bay accounted for over 40% of the total area of the layer .
3 horizontal multi-layer brick wall fewer residential building , when required to take measures to strengthen the seismic capacity and to meet the requirements , the height and number of layers specified in Table 7.1.2 shall be permitted based upon adoption .
[ Revision Notes ]
This section complements the height and number of layers of the multi- control requirements belong to Group B masonry structure housing.
