The Public Works Department (PWD) is the building, housing, road and carparking authority in Singapore. One of its key objectives is to create an orderly built environment through high standards of building control.
This paper is concerned with experimental investigations carried out to study the ultimate load behaviour of I-beam to box-column connections stiffened externally. Eight specimens were tested to failure under monotonically increasing load. Different types of stiffener (i.e. external T-stiffeners and angle stiffeners and internal continuity plate stiffeeners) were considered in the studies. The connections in all cases were made by butt welding. Ultimate loadcarrying capacity and load-defection characteristics of these specimens obtained experimentally are compared with the corresponding results obtained by using a non-linear finite element model. Comparisons are also made between the results for different types of stiffener. Different modes of failure for these specimens were observed. T-stiffeners are found to be the most efficient form.

Singapore, an island city with a land area of only 640 km2 and with a present population approaching 3M, achieved independence only in 1965. The need to ensure sustainable development resulted in a nationwide programme for industrialisation. However, the lack of natural resources and the shortage of cheap labour, which became critical in the 1980s, inevitably culminated in the country’s approach towards high-tech, high value-added industries.
