7.1.3 common brick , brick and masonry bearing small -storey house , should not exceed 3.6m; bottom frame - bottom storey house and within the framework of shear wall buildings should not exceed 4.5m.
7.1.3 common brick , brick and masonry bearing small -storey house , should not exceed 3.6m; bottom frame - bottom storey house and within the framework of shear wall buildings should not exceed 4.5m.
Note : When using the feature really necessary , the use of constraint -storey masonry and other measures to strengthen the common brick wall should not exceed 3.9m.
[ Revision Notes ]
As an exception, this section complements storey masonry structure using 3.9m conditions.
Architecture 7.1.7 multistory masonry buildings , shall meet the following requirements:
One should give priority to cross- load-bearing walls or vertical and horizontal load-bearing walls common architecture .
Uniform wall 2 should be disposed symmetrical aspect , preferably along a plane aligned vertically to be vertically continuous ; the same axis between the walls of the window width should be uniform.
3 houses one of the following conditions should be set when the earthquake seam, seam sides should set up the wall , the height of the slit width should be determined according to the intensity and housing , can be 50 ~ 100mm:
1 ) Building facade elevation above 6m ;
2 ) There are split-level house , and the floor height is relatively large;
3 ) that the structural stiffness, mass different.
4 stairwells should not be set at the far end, and the corner of the house .
5 flue duct, rubbish , etc. should not weaken the wall channel ; When the wall is weakened , coping measures taken to strengthen the wall ; vertical reinforcement should not be used without a chimney attached to the wall and the roof of the chimney.
Fewer six school buildings, hospitals and other cross walls, larger span houses , should adopt situ reinforced concrete floor , roof .
7 should not be used without anchoring precast reinforced concrete cornice .
[ Revision Notes ]
This section complements the teaching buildings, hospitals and other less horizontal wall building, masonry house roof system requirements in order to strengthen small transverse wall , floor houses a large span roof and integrity.
7.3.1 Multilayer common brick , brick house , the following requirements shall be set -situ reinforced concrete structural columns ( hereinafter referred to as structural columns ) :
A structural column settings area, under normal circumstances should be consistent with the requirements of Table 7.3.1 .
2 gallery type and multi -sided corridor -style houses , houses should be based on the number of layers increases after layer , according to the requirements of Table 7.3.1 is set structural columns and vertical walls on both sides of the corridor should be one-sided press facades treatment .
3 school buildings, hospitals and other less horizontal wall houses , houses should be based on the number of layers increases after layer , according to the requirements of Table 7.3.1 is set structural columns ; When school buildings, hospitals and other buildings is less horizontal wall outside Gallery type or style when one side corridor , should be required to set structural columns 2 , 6 degrees but not more than four , seven layers of not more than three and not more than two-story , two-story should be increased after 8 degrees treat .
[ Revision Notes ]
This section increases the stairwell exterior wall corners and irregular plane corresponding 6 degrees fortification corner ( lobes ) of the requirements set structural columns . Up and down the stairs at the end of the wall segments corresponding to an increase of four structural columns , and structural columns set in the stairwell corners together, there were eight structural columns , and then with Article 7.3.8 of the reinforced concrete floor with a half-height , etc. may constitute an emergency evacuation refuges .
