Cantilever spar cable-stayed bridge Cantilever spar cable-stayed bridge A cantilever spar cable-stayed bridge is a modern variation of the cable-stayed bridge. This design has been pioneered by the structural engineer Santiago Calatrava in 1992 with the Puente del Alamillo in Seville, Spain. In two of his designs the force distribution does not depend solely upon the cantilever action of the spar (pylon); the angle of the spar away from the bridge and the weight distribution in the spar serve to reduce the overturning forces applied to the footing of the spar. In contrast, in his swinging Puente de la Mujer design (2002), the spar

Pontoon strategy is far more difficult than Blackjack, however, casinos do not generally object to people using strategy charts at the table. Pontoon strategy is very similar to Spanish 21 strategy, but there are some crucial differences, mainly due to the no-hole-card rule, and the limitations on soft doubling. Pontoon does, on average, have a lower house edge than its American counterparts because of the no-hole-card rule, which means
