《Table 2A comparison of the technologies used to build eight SCFLs with a BIT combination.》
Although these eight BIT combination projects include only two suspension bridges,major contributions have been made to bridge construction technology by the development of sea-crossing suspension bridges with long spans.The western section of the San Francisco–Oakland Bay Bridge contains two single main-span suspension bridge units with 701 m spans—the second longest at that time.These units were built and then connected by means of a central shared anchor block,as shown in Fig.2(a),which was an excellent method at that time of maintaining the balance in terms of mechanics while reducing the costs[4].Further progress in suspension bridges led to the development of a multiple main-span suspension bridge,which is a suspension bridge with two side spans,several main spans,and only two anchors on both ends;there is no additional anchor anywhere,as shown in Fig.2(b)[9].The other contribution of suspension bridge technology is the creation of a new world record in span length:The box girder suspension bridge in the Great Belt Fixed Link is 1624 m in length,and is further characterized by wind-resistance technology for flutter and VIV control with corner deflectors[10].
