Abstract Chemical burns account for a small percentage of burn patients, and there are even fewer burn patients suffering from chemical burns combined with inhalation injury. As chemical substances corrode the airway, which leads to persistent necrotic shedding of the respiratory mucosa and scarring contracture as the airway heals, a proportion of patients develop airway stenosis, requiring more aggressive treatment or even surgery. A 38‐year‐old female chemical factory worker sustained an inhalation injury due to exposure to reactive substances (liquid and smoke) during production. She developed third‐ to fourth‐grade airway stenosis and dyspnoea 2 months postinjury. Interhospital consultation led to referral to the Second Affiliated Hospital of Xi'an Jiaotong University for tracheotomy and endotracheal stent implantation. Postoperative dyspnoea improved, and regular follow‐up was performed. The treatment process of this patient has provided us with valuable experience in the initial management and respiratory tract care of chemical burn patients.

This paper proposes a novel tuned mass damper (TMD) embedded in hollow slabs of civil structures. The hollow slabs in this context, also referred to as “voided biaxial reinforced concrete slabs,” feature a large interior space of prefabricated voided modules that are necessary in the construction of this special structural system. In this regard, a tuned rolling mass damper system (“TRoMaDaS”) is newly proposed, in combination with hollow slabs, to act as an ensemble passive damping device mitigating structural responses. The main advantage of this TMD configuration lies in its capacity to maintain architectural integrity. To further investigate the potential application of the proposed TRoMaDaS in seismic response mitigation, theoretical and numerical studies, including deterministic and stochastic analyses, were performed. They were achieved by deterministic dynamic modeling using Lagrange’s equation and the statistical linearization method. Finally, the promising control efficacy obtained from the deterministic/stochastic analysis confirmed the potential application of this newly proposed control device.
