超高性能混凝土(UHPC)是新一代混凝土,具有卓越的抗壓強度、高延展性、和耐久性。本研究旨在研究薄殼結構使用超高性能混凝土與傳統混凝土相比在設計鋼筋量、混凝土用量差異,並評估其使用效益。經由研究案例建立結構模型,依據結構分析軟體之設計結果表明,薄殼結構在相同的載重條件下,在相同的結構元素超高性能混凝土承受的彎矩內力較小,驗證超高性能混凝土的抗彎強度優於傳統混凝土,可使設計鋼筋量、混凝土用量更少,薄殼結構可以更輕更薄。UHP在抗壓強度、抗拉強度、抗彎強度、延展性、耐久性、減少材料消耗、抑制裂縫發展、維護成本等面向具有優於傳統混凝土的優勢,充分顯示出UHPC在薄殼結構中具有巨大的應用潛力。
Ultra-High Performance Concrete (UHPC) is a new generation of concrete known for its excellent compressive strength, high ductility, and durability. This study aims to investigate the design differences in steel reinforcement and concrete consumption between thin shell structures using UHPC and conventional concrete, and evaluate their benefits. By establishing a structural model through research cases, the design results from structural analysis software demonstrate that under the same load conditions, thin shell structures using UHPC exhibit lower bending moment forces on the same structural elements compared to conventional concrete. This verifies that UHPC has superior flexural strength to traditional concrete, allowing for reduced amounts of steel reinforcement and concrete consumption, resulting in lighter and thinner thin shell structures. UHPC has significant advantages over conventional concrete in terms of compressive strength, tensile strength, flexural strength, ductility, durability, material consumption reduction, crack suppression, and maintenance costs, highlighting the enormous potential for UHPC application in thin shell structures.
