Practical Approach for Design of Semi-rigid Composite Frames

摘要

Although the benefits of semi-rigid connection and composite action of slab are extensively documented in the design of steel frames, they are not widely used much in practice. The primary cause is lack of appropriate practical design methods. In this paper, a practical approach for the design of semi-rigid composite frames under vertical loads and horizontal loads is proposed. The proposed approach provides the design of frame beams and columns for semi-rigid composite frames at the limit states of load-bearing capacity and serviceability. The proposed approach not only takes into account the actual behavior of the beam-to-column connections and its influence on the behavior of the overall structures, but also is simple and convenient for designer to use in engineering practice.
