Severe damage to steel space structures is rarely reported when compared to other structural systems damaged during past major earthquakes around the world. Two gymnasiums of steel space structures in downtown Lushan County that were damaged during the 2013 M7.0 Lushan earthquake in China were investigated and the observations are summarized in this paper. Typical damage to these two steel space structures ranges from moderate to severe. Moderate damage includes global buckling and dislocation of bolted connections of truss members, and inelastic elongation of anchor bolts and sliding of pedestal plates of supports. Severe damage includes member fracture caused by local buckling, and fracture failure of anchor bolts and welds. The distribution of structural damage to these two structures is described in detail and future research opportunities are suggested.

利用ANSYS软件建立螺栓球节点与钢管杆组合构件的有限元模型,采用接触模拟法计算螺栓球钢管构件的屈曲特征值,分析螺栓球节点作为杆件两端约束时对杆件临界荷载产生的影响;参数化研究螺栓半径、套筒壁厚、封板厚度、螺栓头半径和套筒长度等因素对不同长细比杆件屈曲特征值的影响;基于杆件屈曲的欧拉公式,通过回归分析获得考虑螺栓球节点参数与杆件长细比影响杆件的屈曲特征值计算公式。结果表明:随螺栓半径和套筒壁厚增大杆件屈曲特征值显著增大,螺栓头半径对其的影响可忽略不计,封板厚度的增加和套筒长度的减小也能使杆件屈曲特征值有所增加;随杆件长细比的增大,以上各因素对杆件屈曲特征值的影响均逐渐减小,同时杆件长细比越大螺栓球节点对杆件的约束越强;利用回归分析获得组合构件屈曲特征值公式的计算值与有限元结果接近,随节点参数与杆件长细比的变化趋势一致,该公式能够较精准地计算杆件屈曲特征值。

介绍了一种基于"分流器+光纤传输"技术的高压直流电流传变系统。与利用铁芯线圈电磁效应的传统直流测量系统原理不同,该系统利用分流器测量直流电流,在高压侧把测量信号转换为光信号,利用光纤将信号从高压侧传输到低压侧,既克服了传统测量暂态性、抗饱和能力较差的缺点,又很好地解决了高低压侧之间的信号隔离问题。由分流器、导电连接等元件组成的一次电流传感器是该系统的关键组件,由于分流器输出为极易受干扰的毫伏级电压信号,在分析了温升、集肤效应、膨胀应力和结构设计等因素对测量精度所造成的影响后,提出了一次电流传感器的实现方案。最后,通过建模仿真和试验验证了该方案设计合理,精度、温升等主要指标满足我国高压直流传变系统的需求。

脂溶性贝类毒素分布广泛,可通过食物链传递,对消费者健康构成巨大威胁。广西北部湾海域是我国重要的海水养殖区,其贝类产量占比超过一半。为评估广西北部湾沿海居民因摄食贝类而引起的脂溶性贝类毒素摄入风险,并为建立毒素限量标准提供科学依据,采用液相色谱串联质谱法(LC-MS/MS)分析脂溶性贝类毒素含量,24 h膳食回顾法调查居民连续7 d的海产品进食情况,应用海洋生物毒素点评估方法,计算膳食中每日毒素摄入量(Estimated daily intake,ESI),对照欧洲食品安全局推荐的急性参考剂量(Acute reference dose,ARfD)值,评价其食用安全性。结果显示:检出的4种毒素含量均低于欧盟规定的安全限量值。检出率由高到低依次为环亚胺类毒素(Gymnodimine,GYM)(83.02%)、大田软海绵酸(Okadaic acid,OA)(51.16%)、鳍藻毒素(Dinophysis toxin,DTX-2)(40.91%)和虾夷扇贝毒素(Homo�yessotoxin,Homo-YTX)(8.6%),检出的最高质量分数分别为105.4、31.39、38.19和159.66μg·kg^(−1);毒素含量存在季节和物种差异,牡蛎秋季GYM含量最高,冬季OA含量最高。DTX-2更易在秋冬季样品中检出,Homo-YTX仅在夏秋季扇贝和贻贝样品中检出。膳食调查结果显示当地居民贝肉日平均消费量为45 g·d^(−1)。以当地居民贝肉食用量和人体质量估算,OA组毒素ESI值为0.26μg·(kg·d)^(−1),小于欧盟规定的ARfD值[0.3μg·(kg·d)^(−1)]。但若以欧盟提供的贝肉食用量和人体质量数据估算,ESI值[0.34μg·(kg·d)^(−1)]则高于ARfD值。研究表明,虽然广西北部湾沿海市售贝类产品中脂溶性贝类毒素检出值低于欧盟规定的安全限量值,但当地居民存在OA组毒素膳食暴露风险。

2013年4月20日在四川省雅安市芦山县发生了7.0级地震,地震造成196人死亡和21人失踪,经济损失亦极其巨大。此次地震中一些大跨空间钢结构发生较显著的破坏,这是与以往历次震害最大的不同之处。文中总结了芦山体育馆和芦山中学体育馆这两个大跨空间钢结构在此次地震作用下结构发生破坏的主要部位和典型的破坏模式,并分析造成这些破坏的主要原因。针对芦山县体育馆进行现场实测,并与震害结果进行对比,结果表明,结构发生了较明显的扭转现象。以芦山县中学体育馆为例,通过有限元软件ANSYS对其地震下的破坏机理进行数值模拟,并与实际震害进行对比分析。在此基础上,对大跨空间钢结构的抗震设计和施工提出一些合理的意见和建议。

以故宫博物院雨花阁为例,通过振动台试验获得了其在不同强度地震作用下的结构动力响应和震害现象。基于震害与试验数据分析结果指出:试验模型主体结构在强地震作用下无明显震害,但楼层动力放大效应明显,塔顶出现鞭梢效应,底层相对位移较大,位移敏感型和加速度敏感型非结构构件文物均存在地震安全隐患。随着地震动输入的增加,榫卯节点的材料塑性损伤和松动效应增加,结构连接刚度减弱,榫卯的耗能能力增强。这引起基频的逐渐降低和等效阻尼比的增加,等效阻尼比的增加减小了结构的动力反应,提高了木结构的抗震性能。
