Abstract: The initial rotational stiffness of connections is important for the design of semirigid frames. However, most current studies on steel beam to concrete-filled steel tube column connections with bidirectional bolts are ...

Abstract: AbstractExisting research and standards lack a classification method for the diaphragm stiffness of modular steel buildings, which is crucial to identify whether a rigid diaphragm assumption can be adopted during seismic ...

Abstract: In vibration-based damage identification, a common problem is that modal information is not enough and insensitive to local damage. To solve this problem, an effective method is to increase the amount of modal information ...
