Description
Technical field
The present invention relates to the civil engineering work field, belong to the earthquake resistant structure form of band conversion layer structure in the building construction, particularly relate to imitative truss-like damper structure conversion layer.
Background technology
Since the scholar in the former Soviet Union and Eastern Europe proposes the design concept with conversion layer structure first in twentieth century five, the sixties, built the highrise building of many band conversion layers all over the world.Transition form commonly used at present mainly contains following several kinds: transfer beam structure, slab transformational structure, box-shaped transformational structure, truss-like transformational structure.
Built the highrise building of a large amount of band conversion layers both at home and abroad in the last few years; And the transfer beam storey building furtherd investigate; The correlative study document has: Tong Liping; Well is beautiful heavy, and the high level of band conversion layer is built the anti-seismic performance research [J] of irregular structure system. world's earthquake engineering 2008,24 (3): 25-29; Fu Xueyi. band conversion layer Designing Structures of High Rising Buildings suggestions [J]. building structure journal, 1999,20 (2): 28-42; The appearance space, Wei Lian, Ding Dajun. the application of conversion layer structure and development [J] in the highrise building. building structure, 1997, (1): 21-41.These documents carry out theoretical experimental study analysis to the highrise building of band conversion layer, and result of study shows: transfer beam structure force path is clear and definite, stress performance good, simple structure, easy construction, therefore is a kind of Structure Conversion form commonly used at present.
Xu Peifu etc. have carried out a series of test and theoretical research to the anti-seismic performance of bottom large space shear wall structure; Discover; The scantling of transfer beam is big, from great, uneconomical; Be prone to cause the upper and lower stiffness layer sudden change of conversion layer, conversion layer interlaminar shear and relative storey displacement are bigger, so the anti-horizontal earthquake ability of structure is relatively poor.(list of references: Xu Peifu etc. the seismic design [J] of bottom large space upper strata plshy bone open shear wall structure. building science, 1986, (4); Lu Haoliang, Li Siming, Jin nation's virtue. shear wall with short piers shock test and analysis [J] on the highrise building conversion beam. earthquake engineering and engineering vibration, 2005,25 (2): 77-81; Xu Peifu, Hao Ruikun, Wu Lian kind etc. bottom large space shear wall structure seismic design [J]. building science, 1985, (1): 26-37; Hao Ruikun, Xu Peifu, yellow Baoqing etc. bottom large space shear wall structure Floor 12 model pseudo [J]. building science, 1985, (1): 38-52; Mee, A.L, Jordan, I.
