“桑美”台风重灾区疾病监测工作调查

目的通过了解台风灾后疾病监测工作开展情况，探索适合灾区的疾病监测方案。方法对超强台风“桑美”重灾区进行现场调查及对医疗机构负责人和医务人员访谈。结果台风对灾区造成的公共影响较大，尤其是传染病流行风险大大增加，对腹泻病人和发热病人的监测能及时发现传染病人。结论台风灾后应采取灵敏性更高的症状监测，以便及时发现传染病病人，采取控制措施防止疫情蔓延。     

Full-Scale Measurements of Translational and Torsional Dynamics Characteristics of a High-Rise Building during Typhoon Sarika

The field measurement of wind-induced response is of great significance to the wind resistance design of high-rise buildings, in particular torsional responses measured from high-rise buildings under typhoons. The measured high-rise building, with a height of 108 m, has 32 stories and is supported by giant trusses with four massive columns. Acceleration responses along translational and torsional directions were monitored synchronously and continuously during the passage of Typhoon Sarika on 18 October 2016. The wind speed and wind direction at the height of 115 m, the translational accelerations on a total of six floors and the angular accelerations on a total of four floors were recorded. The time and frequency domain characteristics of translational acceleration and torsional angular accelerations were analyzed. The amplitude-dependent translational and torsional modal frequencies of the measured building were identified by NExT-ERA, SSI, and RDT methods. The full-scale study is expected to provide useful information on the wind-resistant design of high-rise buildings in typhoon-prone regions.
