高延性纤维增强水泥基复合材料(ECC)是一种高强度、高延性的新型建筑材料,在加固工程中具有广泛的应用前景。本文利用ECC的高延性和抗剪性,提出一种采用ECC面层加固小雁塔的保护方案,以提高古塔抗震性能;通过有限元软件ANSYS进行模拟分析,比较了小雁塔加固前后的地震响应。分析结果表明:采用ECC面层加固可显著增强塔身整体的延性和承载力,有效地提高塔体损伤容限,为ECC在古塔抗震加固的实际应用中提供借鉴,可作为古塔抗震保护的新途径。
High ductility fiber reinforced cement-based composites (ECC) is a kind of new building material with high strength and high ductility. It has a wide range of applications in reinforcement engineering. Based on the high ductility and shearing resistance of ECC, this paper proposes a protection scheme using ECC surface to reinforce the small wild Goose Pagoda in order to improve the anti-seismic performance of ancient pagoda. The finite element software ANSYS is used to simulate and analyze the structure of the Small Wild Goose Pagoda Earthquake response. The analysis results show that the ECC surface layer reinforcement can significantly enhance the ductility and bearing capacity of the tower body as a whole, effectively improve the damage tolerance of the tower body, provide reference for the practical application of ECC in the anti-seismic reinforcement of the ancient tower, and can be used as the anti-seismic protection of the ancient tower The new way.
