Structural Steel Semirigid Connections: Theory, Design, and Software

Through this study, a method is presented to estimate moment-rotation M- curve of I beam-to-the concrete filled tube CFT connections. This method is based on the components method in which components are analyzed and modeled as different mechanical models. These components are considered as springs with specific mechanical properties of stiffness, strength, and rigid bars. Their force-displacement relationship is assumed bi-linear and 3-linear. The connection behavior is assumed through assembling the stiffness of different components. In this study, connection of I beam-to-CFT column with bolted endplate connection under monotonic loading, which has been tested in the laboratory, is evaluated. It must be mentioned that those bolts which penetrated into the column depth have been used in order to create continuity between flanges of the column.

Considering the nonlinear behaviors of semi-rigid connections, a new calculation model for the second order elastic-plastic analysis of plane steel structures is presented by replacing the general element with a new one, which has two rotational springs at its ends. And the second order elastic-plastic program of this kind of structure is worked out. Two steel frames are calculated with this program. The results of calculations show that this model is reliable and fit to the analysis of all plane steel structures. Request Permissions. New York

Traditionally connections are classified as pinned or rigid, but in actual practice most of the connections fall under semi-rigid category. The design procedures for semi-rigid connections are more tedious but prove to be more economical. The top and seat angle connection which have been traditionally considered as a pinned connection for simplifying frame analysis is found to exhibit semi-rigid behaviour. In the present paper, an all-bolted top and seat angle connection is investigated in detail using the software ANSYS The effect of geometric parameters on the monotonic moment—rotation relationship is discussed.

Althoughthe semirigidity concept was introduced many years ago, steel structures are usually designed byassuming that beam-to-column joints are either pinned or rigid. Theses assumptions allow a greatsimplification in structural analysis and design-but they neglect the true behavior of joints. Theeconomic and structural benefits of semirigid joints are well known and much has been written abouttheir use in braced frames. However, they are seldom used by designers, because most semirigidconnections have highly nonlinear behavior, so that the analysis and design of frames using them isdifficult. In fact, the design problem becomes more difficult as soon as the true rotational behavior ofbeam-to-column joints is accounted for-the design problem requires many attempts to achieve asafe and economical solution.
