Innovative Bridge Structures Based on Ultra-High Performance Concrete (UHPC)

Innovative Bridge Structures Based on Ultra-High Performance Concrete (UHPC): Theory, Experiments and Applications introduces more than a dozen innovative bridge structures and some engineering applications developed by the author's team based on UHPC. Recent studies have shown that the application of UHPC is expected to greatly reduce the amount of materials and carbon emissions, and prolong the life of the structure. After calculation, when UHPC is applied to the arch bridge with compression as the main stress characteristic, compared with the steel arch bridge, the dead weight of the UHPC arch bridge is basically the same, and the cost and carbon emission are only 34% and 20% of the latter; Compared with the concrete arch bridge, the cost is the same, and the weight and carbon emissions are only 1/3 of the latter. When applied to other types of bridges, the carbon emissions of UHPC bridges are 40% of those of steel bridges and 54% of those of concrete bridges, and the UHPC structure is expected to last up to 200 years. It can be seen that the new bridge structure developed by UHPC can make outstanding contributions to the realization of the "carbon peaking and carbon neutrality goals" and "sustainable development". Ultra-high performance concrete (UHPC), as a new generation of civil structural materials, has the characteristics of high strength, high toughness and high durability. Through the collaborative innovation of new materials and new structures, the application of UHPC in bridge engineering is expected to achieve the goal of economical, environmentally friendly, durable and high performance of the main structure, and to solve the common problems of many structural diseases, short life, large carbon emissions, and high cost. This book introduces some of the work done by the author's team in this field and its application in bridge engineering.
