Connection design

It is important that connections for blast loaded members have sufficient rotation capacity, A connection may have sufficient strength to resist the applied load however, when significant deformation of the member occurs this capacity may be reduced due to buckling of stiffeners, flanges, etc. Figure 10.1 is an example of a connection design for large rotation capacity. 

Connections - Design to develop ultimate strength of the members being connected. Peak member end forces from the frame analysis can be used however, this can be extremely conservative since the peak force occurs for only a short time. 

When specified, proposed connection designs shall be submitted to the pnrchaser for approval before fabrication. The drawing shall show weld designs, size, materials, and preweld and postweld heat treatments.

For the basic glass/glass configuration, two series connection designs are possible. These are described below. 

Figure 5.2 shows the influence of dead volume and connection design on the peak distortion and dead time of the HPLC unit. Three runs were performed with the same flow rate and sample size (injection time 2 s). The straight black line describes the elution profile of a tracer in an optimal system with small dead volume and optimal connections. In the next example one of the tube connections was insufficient because, within the connector, the tube endings did not touch and a small dead volume is formed. The dashed line shows the new elution profile. A poor connection results in higher backmixing and, thus, peak distortion. This effect should be kept in mind for systems with many connections.

Connectivity and stereoisomerism give chemists a way to uniquely differentiate one molecular structure from another. The molecular formula C4H9Br, for instance, represents five different substances (see Figure 4). Predictably, although there is only one compound for each of the connectivities designated 1-bromobutane, 2-bromo-2-methylpropane, and...

The definitions given in the EUROCOMP Design Code relating to connection design are based on or taken from References 5.1, 5.2, 5.3, 5.4 and 5.5. Some of the definitions have been developed specifically for the EUROCOMP Design Code. 

The hierarchical categorisation of different connections illustrated in Figure 5.1 of the EUROCOMP Design Code forms the basis of how the connection design part has been structured. It also defines the basic terminology used on each hierarchical level. 

The partial safety factors given in the EUROCOMP Design Code are based on the earlier experience and general knowledge on connection design of the EUROCOMP member participants. They are not based on any specific tests or analysis.
