Abstract

In recent development, British Standard BS 5950:2000 and Eurocode 3 offer the opportunity to design steel frames as ‘semi-continuous’ by including the moment resistance of ‘partial strength’ connections in plastic hinge analysis of the frame. Such design method offers various benefits for braced frames such as shallower and lighter beams, standardized connections with less complicated geometry, and more robust frames compared to simple construction. It is also expected to give significant savings in frame weight. This paper presents parametric study findings on a series of two-bay, four-bay and six-bay braced frames of two-, four-, six- and eightstorey with span ranging from 6 m to 9 m, by comparing between Hot-rolled (HR) steel beams designed using simple construction and Trapezoidal Web Profiled (TWP) steel beams designed using the semi-continuous construction method. Flush end-plate and extended end-plate connections were used as partial strength joints whereas for the simple construction, partial depth flexible end-plate connections were used as pin joints. The semi-continuous design method can reduce the frame weight between 13.4% and 20.5% compared to simple construction.
