Abstract

The findings of a recent survey on the steel roof structure of an early-twentieth-century building located in Sofia, Bulgaria are reported. The steel roof structure is supported by solid masonry walls around the building perimeter and on slender cast-iron columns along two interior longitudinal lines. The south part of the building was severely damaged during the bombing raids over Sofia in WWII. The building underwent a major refurbishment within the 1995-2000 period accompanied by detailed survey and condition assessment of the steel roof structure. In 2020 the authors carried out a survey for condition assessment of the steel roof structure including checks of riveted connections, analysis of chemical composition by OES metal analyser and inspection of the roof cladding components by endoscopic device.
保加利亚索非亚遗产建筑钢铆接屋面状态评估
本文报道了最近对保加利亚索非亚一座20世纪早期建筑的钢屋顶结构的调查结果。钢屋顶结构由建筑周边的实心砖石墙和沿着两条内部纵线的细长铸铁柱支撑。这座建筑的南部在二战期间对索非亚的轰炸中遭到严重破坏。该建筑在1995年至2000年期间进行了一次重大翻新,并对钢屋顶结构进行了详细的调查和状况评估。2020年,作者对钢屋顶结构进行了状态评估调查,包括铆接连接检查,OES金属分析仪分析化学成分,内窥镜设备检查屋顶包层成分。
