Integrated Design System for Semi-Rigidly Connected Steel Frames

Integrated Design System for Semi-Rigidly Connected Steel Frames A prototype Integrated Design System (IDS) for semi-rigid steel frames is reported. The aim of this system is: (i) to assist designers in conducting the overall analysis required for the frames, (ii) to provide designers with a tool to design the frames economically in terms of the total cost of the frame. The system works by guiding the users towards appropriate design decisions that recognise the cost of the frames — not just material costs but also fabrication costs. Recognition of the semi-rigid and partial strength characteristics of beam-to-column connections means that the internal force distribution in a frame depends on the analysis method adopted. A successful design for a frame requires a balanced internal force distribution between the connections and the members. To assist in achieving this, a number of analysis methods have been incorporated into the system. A detailed economic appraisal of semi-rigid frame designs is presented by means of a worked example. This illustrates global comparisons between the use of alternative analysis methods as well as between alternative options in the detailing of the connections. The benefits that can be obtained from using the system at both the conceptual and the detailed design stages are demonstrated. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Advances in Structural Engineering SAGE

Abstract

A prototype Integrated Design System (IDS) for semi-rigid steel frames is reported. The aim of this system is: (i) to assist designers in conducting the overall analysis required for the frames, (ii) to provide designers with a tool to design the frames economically in terms of the total cost of the frame. The system works by guiding the users towards appropriate design decisions that recognise the cost of the frames — not just material costs but also fabrication costs. Recognition of the semi-rigid and partial strength characteristics of beam-to-column connections means that the internal force distribution in a frame depends on the analysis method adopted. A successful design for a frame requires a balanced internal force distribution between the connections and the members. To assist in achieving this, a number of analysis methods have been incorporated into the system. A detailed economic appraisal of semi-rigid frame designs is presented by means of a worked example. This illustrates global comparisons between the use of alternative analysis methods as well as between alternative options in the detailing of the connections. The benefits that can be obtained from using the system at both the conceptual and the detailed design stages are demonstrated.
