In order to investigate the seismic and fire resistance performance of hot-rolled SQ460FRW steel, the steel was kept at a temperature range from 250 ℃ to 650 ℃ for 1 hour to simulate fire environment, and the microstructure evolution and seismic and fire resistance performance of SQ460FRW steel after different heat treatment were analyzed. The results show that granular bainite (GB) and ferrite (F) can be observed in SQ460FRW steel before and after high-temperature heat treatment, but the degree of decomposition of martensite/austenite (M/A) islands in microstructure is different. After heat treatment at 250-650 ℃, internal friction curve of SQ460FRW steel shows that the SKK peak gradually decreases from 3.926 × 10^-4 to 1.348 × 10^-4, and the carbide precipitation gradually increases from 8.78% to 65.96%. Compared to hot-rolled SQ460FRW steel, SQ460FRW steel has little change in its strength and plasticity after heat treatment at low-temperature (250 ℃) and medium temperature (350 ℃), but has remarkably higher yield strength and increased yield ratio after heat treatment at or above 450 ℃. It is shown that SQ460FRW has its yield ratio less than 0.85 after treatment at or below 550 ℃. After treatment at 250-550 ℃ for 1 h, SQ460FRW steel can have its tensile properties up to the requirements for earthquake and fire resistant steel in GB/T 19879—2023 and GB/T 28415—2023 standards, and it can have higher strength after treatment at 550 ℃. It is concluded that after SQ460FRW steel for construction is heat-treated at 250-650 ℃, its yield ratio exhibits a negative linear correlation with room-temperature internal friction.

为了考察热轧态SQ460FRW钢的抗震耐火性能，模拟火灾环境对热轧态SQ460FRW钢实施了250~650 ℃、保温1 h的热处理，并对不同热处理态SQ460FRW钢的微观组织演变和抗震耐火性能进行了分析。结果表明，高温热处理前后SQ460FRW钢中都可见粒状贝氏体和铁素体，但是组织中马氏体/奥氏体小岛组织分解程度不同；内耗法测得250~650 ℃热处理后，SQ460FRW钢的SKK峰值从3.926 × 10^-4逐渐减小至1.348 × 10^-4，碳化物析出量（体积分数）逐渐从8.78%增加至65.96%。相较于热轧态SQ460FRW钢，低温（250 ℃）和中温（350 ℃）热处理后SQ460FRW钢的强塑性变化不大，450 ℃及以上温度热处理后SQ460FRW钢屈服强度明显上升、屈强比增大，550 ℃及以下温度热处理后SQ460FRW钢屈强比小于0.85。250~550 ℃/1 h热处理后，SQ460FRW钢的拉伸性能符合GB/T 19879—2023和GB/T 28415—2023对抗震耐火钢的要求，550 ℃热处理时SQ460FRW钢具有更高的强度。建筑用SQ460FRW钢在不同热处理温度（250~650 ℃）下的屈强比与室温内耗具有线性负相关性。
