Affection Of Location Of The Connective Corridor On The Capability Of Connection Structure And A Simple Method On Weakly Connected Structure

The high-rise building with connective structures includes twin towers or multi-towers connected by a joining (or connective corridor) to a definite height. Under the earthquake, towers which vibrate severally in the case of no connective structures while be an interaction because of the connection. Their responses are more complex than that of a single tower or twin towers without the connective structure,and vibration coupling and torsion increasing will occur. These have caused serious loss in the earthquake (such as the connective corridor damage in Jiji earthquake in Taiwan in 1999). Thus the research on high-rise building with connective structures has a practical significance.This paper is supported by the Research Funds of the Lanzhou University interdiscipline Youth innovation, opening funds of Key Laboratory of Mechanics on Western Disaster and Environment, and the science and technology item of Construction Department in Gansu.First of all, by changing the position of the connection the paper respectively analyzed the effect on strong connection structure when changing the position of the connection for the main structure of 29 storeys , of 25 storeys, of 21 storeys, and of 17 storeys. To find the best location of connecting, research shows that the connection near 0.57 H -0.67H is the best location.Second, the paper analyzed the effect on the weak connection structure when changing the position of the connection. Research shows that the position change of the connection on the weak connection structure has little effect on the Seismic behavior and in the construction programme design, and we may not consider the impact of the location of the connecting to the structure's static and dynamic performances.Third, by comparative analysis between the weak link twin-tower structure and the single tower structure, it verified that in the weak twin towers structural design you can only process single-tower structure design.Finally, this paper gives a simple conclusion on the study, points out the further study direction and specific work to be completed.
