I guess there will always be a debate over cost efficency versus aesthetics. <BR/><BR/>In the case of the Waiwhakaiho, the client did want an "iconic" bridge. Selection was based mainly on price and design with equal weighting. The bridge had to be single span. An arch or truss are probably the most efficent structural system for a span of about 70m. I choose an arch because I felt I could "tune it" into the local context of site, and make the structure a piece of art that has deep meaning especially for the local people. The bridge gives access to sacred land.<BR/><BR/>The vibration criteria for this bridge is BS5400.2:2006, Annex B and the Novare Design Ltd bridge exceeds this criteria.<BR/><BR/>I acknowledge the experience I earned working for Mr Calatrava, and respect him immensely for adding so much to modern day bridge design. The Waiwhakaiho Arch Bridge is however, entirely my own work.<BR/><BR/>If anyone has other queries about this bridge, please contact me at peterm at novaredesign dot com. <BR/><BR/>Best regards<BR/><BR/>Peter MulqueenAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-6470543006314152962.post-37104748089606637632009-02-23T11:34:00.000+00:002009-02-23T11:34:00.000+00:00Dear happypontist,First of all, congratulations fo...Dear happypontist,<BR/><BR/>First of all, congratulations for your excellent blog. I just found it this weekend and have been reading many of your previous posts which I find very interesting.<BR/><BR/>In relation to the current topic, I agree that the structural solution (partcular the deck and "suspension system !!??") is not particulaly efficient and I would find it difficult to see it work due to the torsion in the deck, with or without dynamic effects taken into consideration.<BR/><BR/>Similar pedestrian bridges have been designed and built already in other parts of the world. This one in a city in the north of spain (pontevedra) explores he same principle of a skew arch, but in this case the cable system and deck design is more rational (cut and paste the following link):<BR/><BR/>http://picasaweb.google.com/dearthoir/Pontevedra_pedestrian#<BR/><BR/>Again, great discovery your blog. Keep posting high quality entries in bridge design (I particularly liked Menn and Leonhardt ones).Unknownhttps://www.blogger.com/profile/11804371897477562628noreply@blogger.com
