specific Embodiment approach 1

[0026] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 1 In the drawings, the shear failure-free earthquake-resistant and anti-collapse masonry building of the present invention is provided with a horizontal interface at 1 / 2 height of the building. The interface and the area below are key earthquake-resistant areas. The interface The above are ordinary earthquake-resistant areas. The key earthquake-resistant areas are mainly composed of cave-side masonry seismic walls 3, vertical isolation joints 4, connecting beams 8, ring beams 9, and non-hole masonry walls 14, and cave-side masonry seismic walls 3 and windowsills There is a vertical isolation joint 4 between the wall 1 and the lintel wall 7, and the cave-side masonry seismic wall 3 and the non-hole masonry wall 14 are controlled by the super-strong coefficient η of the seismic shear bearing capacity V Super-strength coefficient η greater than seismic flexural capacity M , Make it show a non-shear failure bending yield mode und...

specific Embodiment approach 2

[0036] Embodiment 2 A horizontal interface is set at 2 / 3 of the height of the building, the interface and the area below are key earthquake-resistant areas, and the area above the interface is ordinary earthquake-resistant areas.

[0037] Said η M When the value is equal to 0.5, increase the rigidity of the connecting beam 8, or adjust and increase the spacing between the vertical segmented joints 15 and the separation hole 16 on the non-hole masonry wall 14, or the masonry seismic wall on the side of the hole. 3. No hole Additional reinforced concrete edge members are added to the horizontal section end of the masonry wall 14 or the masonry seismic wall section 17 to make η M Increase the value to 1.0 or above 1.2.

[0038] Said η V Value is only η M When it is 0.6 times the value, add horizontal shear steel bars in the hole-side masonry seismic wall 3, non-hole masonry wall 14, or masonry seismic wall subsection 17, or add a reinforced concrete shear column in the middle of its ...

specific Embodiment approach 3

[0040] DETAILED DESCRIPTION 3 The horizontal interface is set on the top surface of the building, that is, the entire area of ​​the building is used as a key seismic protection zone.

[0041] Said η M When the value is equal to 0.9, increase the rigidity of the connecting beam 8, or adjust and increase the spacing between the vertical segmented joints 15 and the separation hole 16 on the non-hole masonry wall 14, or the masonry seismic wall on the side of the hole. 3. No hole Additional reinforced concrete edge members are added to the horizontal section end of the masonry wall 14 or the masonry seismic wall section 17 to make η M Increase the value to 1.0 or above 1.2.

[0042] Said η V Value is only η M When the value is 1.0 times, add horizontal shear reinforcement in the hole-side masonry seismic wall 3, non-hole masonry wall 14, or masonry seismic wall subsection 17, or add a reinforced concrete shear column in the middle of the section to increase Seismic shear capacity of t...

Abstract

A cut-damage-free antiseismic collapse resistant masonry building and a building method thereof belong to the antiseismic and disaster preventing technical field of civil construction structure. The invention is characterized in that a masonry wall provided with an isolation joint or an isolation hole is an antiseismic collapse resistant building of cut-damage-free type. An important antiseismic area bends ahead of a common antiseismic area. In building process, a vertical isolation seam is arranged between a window wall, a lintel wall and the masonry antiseismic wall near the hole. When the masonry wall of beeline-shaped section is cut up, the middle of the long side of the section is provided with a vertical stage slot or the isolation hole. The extra strong efficiency of antiseismic bearing capacity of the masonry wall is controlled to make the masonry wall bend in earthquake. Crisp cut and slide of the whole section is avoided. After bending, the bearing capacity and the rigidity have little retrogression and good tensibility. The building has highly efficient collapse resistant capability, can be used for new construction or antiseismic security and antiseismic reinforcement of the existing masonry building. The invention is especially applicable to masonry houses in highly seismic region and reconstruction after earthquake.

Description

Technical field: [0001] The invention relates to a shear-damage-free earthquake-resistant and collapse-resistant masonry building and a construction method thereof, and belongs to the technical field of earthquake-resistant, disaster-preventing and disaster-reduction of civil building structures. Specifically, it relates to a high-efficiency earthquake-resistant and collapse-resistant masonry building with no shear failure, swaying and lodging resistance, and a construction method, especially a masonry building with no reinforcement, structural reinforcement or reinforced reinforcement in a high-intensity earthquake zone or under a strong earthquake The field of high-efficiency anti-fall and disaster prevention technology is mainly used for earthquake and disaster prevention of masonry buildings and civil structural engineering, and more importantly, it is suitable for recovery and reconstruction after the Wenchuan earthquake. Background technique: [0002] Masonry houses are a m...
