EQUFIRE

SERA The Seismology and Earthquake Engineering Research Infrastructure Alliance for Europe (SERA), funded within the Horizon 2020 research and innovation programme of the European Commission under grant agreement no. 730900 Fires following earthquake (FFE) are a considerable threat, this is particularly relevant for steel structures, as the high thermal conductivity leads to a quick temperature rise with consequent fast loss of strength and stiffness. Therefore, an enhanced fire performance can be required in seismic-prone regions and no guidelines are currently available in European standards. The EQUFIRE project studied the response of structural and non-structural components to fire following earthquake scenarios, with a view to improving existing design guidelines and future standards. The project studied a three-bay by three-bay steel structure with four storeys. The lateral bays (in both directions) were 5 m wide, while the central bay hosting the concentric bracing was 2.5 m wide. The inter-storey height was 3 m, with exception of the first floor, the height of which equalled 3.6 m. The experimental activities at the ELSA Reaction Wall included pseudo-dynamic tests on a full-scale specimen of the first storey of the building, while the upper three storeys were numerically simulated. The aim was to study the response of the structure and fire protection elements, including their interaction, under the design earthquake and for different configurations. Four specimen configurations were taken into consideration: bare frame without fire protection, and frame with three alternative fire protection solutions (conventional, seismic-resistant boards, and vermiculite sprayed coating) applied on the bracing and one column. The dataset gathers the signals recorded during the experimental campaign performed at JRC-ELSA.SERA，即欧洲地震学与地震工程研究基础设施联盟（Seismology and Earthquake Engineering Research Infrastructure Alliance for Europe, SERA），由欧盟委员会地平线2020（Horizon 2020）研究与创新计划资助，资助协议编号为730900。 地震次生火灾（Fires following earthquake, FFE）是一类极具破坏性的灾害，该风险对于钢结构建筑尤为显著：因其高热导率特性，会快速引发构件温度升高，进而导致强度与刚度迅速衰减。因此，地震高发区域往往需要更高标准的防火性能，而当前欧洲相关标准中尚未出台对应的设计指南。EQUFIRE项目围绕地震后火灾场景下结构与非结构构件的响应开展研究，以期完善现有设计规范并助力未来标准制定。该项目以一栋3跨×3跨、4层钢结构建筑为研究载体：双向横向柱间距均为5米，设置同心支撑的中央柱间距为2.5米；楼层净高除首层为3.6米外，其余楼层均为3米。 在ELSA反力墙开展的实验工作中，研究人员针对该建筑首层的足尺试件完成了拟动力试验（pseudo-dynamic test），上部三层则通过数值模拟完成分析。本次研究的核心目标是探究结构与防火构件在设计地震作用下的响应及其相互作用，共考虑四种试件配置方案：无防火保护的裸框架，以及分别采用三种不同防火处理方案（常规防火板材、抗震防火板材、蛭石喷涂涂层）对支撑构件与单根柱进行防火处理的框架。 本数据集收录了在JRC-ELSA开展的全部试验活动中记录的各类信号数据。
