    超高性能混凝土全生命周期减碳是否抵消高材料碳排2 个问题

    1. Service-life-integrated whole-life LCA of concrete structures: a unified uncertainty-quantified framework, full life-cycle CO2 uptake, and the generality of green-concrete ranking inversions across deterioration mechanisms

    2. Robust whole-life environmental quantification of strength increase in concrete bridges: durability-driven service life, maintenance-scenario uncertainty, and end-of-life crediting

    钢筋混凝土尺寸效应在不同断裂模型中的预测差异2 个问题

    1. Fictitious crack length and effective process-zone size versus aggregate microstructure in size and boundary effect models for concrete fracture

    2. Fracture-mechanics basis for minimum mesh (shrinkage-and-temperature) reinforcement in concrete: closed-form minimum ratio, experimental validation of size-effect suppression, and extension to more complex configurations

    剪切破坏承载力公式跨规范不一致4 个问题

    1. Rational evaluation and mechanism-informed calibration of code shear design provisions for reinforced recycled aggregate concrete beams with stirrups

    2. Recalibration of the IS 456:2000 concrete shear contribution provisions for reinforced concrete beams

    3. Shear strength design formulation for high-strength concrete beams: correcting the partition between concrete and stirrup contributions and the stirrup-yielding failure assumption

    4. A size-effect-inclusive shear strength model and a bond-versus-web-shear failure criterion for full-scale precast prestressed double tees

    结构健康监测中的温度效应与损伤信号混淆2 个问题

    1. Field validation and data-length/sensing requirements of damage detection from temperature-separated quasi-static structural monitoring responses (adaptive bandwidth filter approach)

    2. Deployment readiness of the temperature-based three-dimensional baseline for long-span-bridge structural health monitoring: timing, thermal realism, and generalizability

    近断层脉冲地震动对高层结构响应的放大机制2 个问题

    1. Velocity-pulse effects on long-period inelastic response spectra: robustness across record suites, sensitivity to the record-synthesis method, and design-spectrum implications

    2. Predictive design relationships for near-fault pulse amplification of seismic demands in inter-storey-isolated buildings: regression of amplification and displacement-correction factors on bearing period, damping, and substructure flexibility, and the role of pulse arrival timing
