另一方面，五螺箍RC柱於塑铰区发挥良好之韧性，五螺箍所围束之混凝土大致保持完好，混凝土保护层并无严重剥落之情形，且主筋亦无明显的挫屈现象，箍筋亦未发生断裂。

It was found in a high-rise building structure after fire that large-area concrete spalled at the bottom of slabs reinforced with low-alloy deformed steel bars. Temperature field of slabs during fire was determined by the ultrasonic-rebound combined method, and post-fire mechanical performance of concrete and steel bars were inspected by drilled cores and intercepted steel bars respectively.

针对某高层建筑结构低合金盘圆变形钢筋混凝土楼板火灾后板底混凝土大面积脱落的情况，现场采用超声回弹综合法确定楼板温度场，钻取芯样测试火灾后混凝土强度，截取钢筋试件通过拉伸试验检测火灾后钢筋力学性能。

The results show that, the chloride concentrations and diffusion coefficients are both a one-humped function of elevations (can also be the time scale of seawater infiltration), they increase with the increase of elevation until they get to the peak value, and then decrease with the increase of elevation; an evident relationship is being between the surface chloride concentrations and the wave forces acted on the concrete surface, while there is no much difference among the diffusion coefficients; the diffusion coefficients get to bigger as the depth from the concrete surface increase in the influence of the capillary structures evolution and chloride concentration, but this tendency of change was alleviated with the increase of depth.

研究结果表明：氯离子侵蚀混凝土设施的竖向分布规律为氯离子浓度、扩散系数与标高之间同为单峰函数分布，先随高程变大而变大，达到峰值后，随高程变大而减小；氯离子侵蚀混凝土设施的环向分布规律为混凝土构件表面氯离子浓度、氯离子通量与波浪力之间有明显的对应关系，波浪力越大，则表面氯离子浓度和氯离子通量越高，而扩散系数在各方位角差别不明显；由于混凝土长期服役过程中内部毛细孔隙结构演化以及氯离子浓度的影响，氯离子扩散系数随混凝土深度变大而变大，但这种变化趋势随深度逐渐趋缓。

In recent years, high performance concrete (HPC, or high strength concrete-HSC) has been widely used in engineering practices such as bridges, runnels, tall buildings, offshore oil platforms and nuclear engineering applications due to its intrinsic properties of high strength, high durability etc. Hence, the prediction of HPC structures performance is of great practical importance, in particular for safety evaluation of HPC structures subjected to fire or other thermal hazard situations.

近年来，随着建筑结构性能要求的提高，高性能混凝土(HPC，或称高强度混凝土HSC)正逐渐蓬勃兴起并替代传统的混凝土用于桥梁、隧道、高层建筑、海洋石油平台和核工业设施等方面，因此对于高性能混凝土结构性能的预测显得十分重要，对火灾或其它高温危险环境下高性能混凝土结构安全性的评估尤其值得重视。
