The paper presents results from several condition surveys of existing steel crane-supporting structures with a focus on the performance of the links of the runway beams to the supporting columns. These links require careful detailing in order to safely transfer the crane lateral forces to the columns and accommodate the beam end rotations. Different types of industrial buildings have been inspected and the major factors contributing to the observed damages are identified. An overview of several typical connections between the runway beams and supporting columns representative of Bulgarian design practice is included along with newly proposed detailing concepts. The analysis of survey findings shows that the amount of the observed damage and failures can be directly related to link detailing. Recommendations are made for improving the long-term performance of the links connecting the steel crane runway beams to the supporting structures via better detailing. |
