Jianzhu Gangjiegou Jinzhan火灾下轴心受压约束钢构件的力学响应复杂，所产生的温度内力导致其耐火极限的确定与计算难度大。为简化结构构件在高温承载极限状态时约束钢构件的防火设计，采用有限元数值模拟方法开展了大量参数分析，以确定火灾高温下轴心受压约束钢构件的承载与失效规律。基于经试验验证的可靠有限元模型，研究了不同长细比、轴向约束刚度比和初始荷载比等参数对轴心受压约束钢构件火灾响应的影响。结果表明，上述参数均将显著影响约束钢构件的火灾响应，且当长细比较大、轴向约束刚度比较小、初始荷载比较大时 ...

Dianci bileiqi氧化锌压敏电阻在重复过电压下性能会逐渐劣化，最终可能导致短路、起火或爆炸，目前单次耐受测试无法全面反映ZnO压敏电阻在实际使用中的预期性能，亟需对其冲击老化特性及失效机理进行深入研究。文中建立了ZnO压敏电阻重复冲击电流试验实验平台，研究了以压敏电压、冲击残压及泄漏电流为表征的ZnO压敏电阻保护特性劣化特性。研究结果表明，压敏电阻的冲击老化寿命随着冲击密度的增加而显著减少，这是由于电阻片尺寸效应引起的微观缺陷增加所致。此外，不同电流幅值条件下的冲击间隔对老化过程也有显著影响 ...
