Previous analytical and experimental work by the authors has determined that integrated shell-deck segments can be used to construct short- or medium-span bridges. This system consisted of integrated shell-deck concrete segments that are post-tensioned together to form a simply supported bridge. A 1:3-scale segmental concrete shell bridge model was tested to failure. The bridge model was subjected to increasing load until failure occurred. Before failure, excessive deflection, cracking, and buckling of some of the steel elements connecting the deck to the shell edge beams were observed. Failure of the model resulted from the formation of excessive diagonal shear cracks in the shell portion of one of the segments. The fabrication and the behavior of the bridge model indicated that shell bridges can be used to construct short- and medium-span segmental bridges.

SummaryWe have prospectively evaluated the biologic response to desmopressin (DDAVP) in 28 children with type 2 von Willebrand disease (VWD) in correlation with the phenotype and the molecular defect of VWF. The diagnosis of VWD type 2 was mainly based on VWF functional parameters and/or an aberrant VWF multimer pattern. Seventeen different mutations were identified (6 of them novel). No response with respect to the functional parameters VWF:RCo and/or VWF:CB was seen in patients with severe abnormality of the VWF multimer pattern. One patient with VWD type 2A phenotype IIC Miami did not respond with respect to VWF:CB, but showed a good response of VWF:Ag and FVIII:C as expected. Interestingly he showed a persistently high level of VWF:Ag and FVIII:C up to 4 hours after DDAVP infusion. Patients with minor alterations of multimer structure and particular mutations responded well to DDAVP, whereas patients with normal multimer structure but a defect in platelet dependent functional parameters did not respond with VWF:RCo. Conclusion: Children with VWD type 2 show a variable response to desmopressin depending on the mutation that correlates with the functional defect and the presence or absence as well as the half-life of large VWF multimers. Our data emphasize the usefulness of DDAVP testing even in patients with VWD type 2, possibly with the exception of VWD type 2B.
