In view of China’s development trend of green building and building industrialization, based on the emerging requirements of the structural engineering community, the development and proposition of novel resource-saving high-performance steel-concrete composite structural systems with adequate safety and durability has become a kernel development trend in structural engineering. This paper provides a state of the art review of China’s cutting-edge research and technologies in steel-concrete composite structures in recent years, including the building engineering, the bridge engineering and the special engineering. This paper summarizes the technical principles and applications of the long-span bi-directional composite structures, the long-span composite transfer structures, the comprehensive crack control technique based on uplift-restricted and slip-permitted (URSP) connectors, the steel plate concrete composite (SPCC) strengthen technique, and the innovative composite joints. By improving and revising traditional structure types, the comprehensive superiority of steel-concrete composite structures is well elicited. The research results also indicate that the high-performance steel-concrete composite structures have a promising popularizing prospect in the future.

珊瑚混凝土(CAC)作为一种新型建筑材料,已经在岛礁工程结构建设领域引起了极大的关注。为了研究CAC的静态劈裂抗拉性能,本文提出了一种考虑骨料形状和空间分布随机性的三维(3D)随机混凝土细观模型,影响因素包括试件形状和支承垫片尺寸。我们建立了12 个不同的混凝土细观模型,按照试件形状可分为两种,即边长为150 mm的立方体和尺寸为ϕ150 mm×300 mm的圆柱体。其中,支承垫片宽度为6 mm、9 mm、12 mm、15 mm、18 mm和20 mm。本文系统分析和讨论了试件几何形状和垫片宽度对CAC劈裂抗拉性能的影响规律,研究内容包括混凝土开裂过程、最终破坏模式和劈裂抗拉强度(fst)。结果表明:本文所开发的细观模型具有很高的可靠性,并确定了适用于CAC劈裂抗拉性能模拟和预测的最优计算参数。CAC的fst值与试件形状和垫片宽度直接相关。其中,在垫片尺寸相同的情况下,立方体CAC试件的fst值要略高于圆柱体模型,表明可以采用断裂面积的差异来解释试件形状效应对CAC fst值的影响规律。此外,当垫片的相对宽度由0.04 增加到0.13 时,CAC的fst值会呈现逐渐增大的趋势。基于弹性力学理论,本文初步确定了不同垫片宽度条件下CAC fst的取值范围,这对于研究CAC的抗拉性能具有重要意义。
