The new method for evaluating the displacement tolerance of sky-bridges with pin-roller type supports was proposed considering both return period of phase difference between connected buildings and geometrical characteristics of skybridge. Because displacement tolerance is relative value, which is most affected by the phase difference of the connected buildings, the dynamic response of these building with time history analysis should be evaluated. However, the initial phase could not be specified, so the result of displacement tolerance would be varied with respect to initial value. Thus, the tolerance can be reasonably evaluated SRSS calculation with design displacements based on statistical approach and of each building. In addition, the geometrical characteristics of sky-bridge should be considered because the transverse displacement of sky-bridge span causes the shear deformation of the bridge and longitudinal displacement tolerance cannot release the shear deformation. Therefore, the some pin-end support in sky-bridge should have longitudinal displacement tolerance to accommodate the shear deformation. By resolving this shear deformation, it is possible not only to accommodate transverse displacement, but also to avoid the complicated joint details such as both pot bearing and guided supports with shear key.

Contemporary hospital has more and more extension because the growth and change of hospital has to respond the various needs. For expanding, the sky bridge(sky walk) becomes one of the method to interconnect two or more buildings on the air. Sometimes the designers don't know exactly how the sky bridge works after construction. Beyond the role of interconnecting two buildings, the role of sky bridge is transformed the main axis of pedestrian in the whole hospital organization. This scope of analysis is about the sky bridge of Hanyang University hospital. The first method is the investigation of the utilization in this time. The second is the analysis of design drawings got form the designing of the past(1994-1998). From this analysis, the conclusions are followings.；The designer who wants to apply the sky bridge should more consider about, 1) how the sky bridge impacts the whole spatial system such as the pedestrian, patients, physicians, service's facilities etc. 2) what the inside of sky bridge has something such as natural light, ventilation, and the height, depth, width of aisle, the sign for seeking orientation. etc. In future the research relating sky bridge should be studied some hospital as well as one hospital for comparing the characteristics of the concepts and organizations
