摘要

准确估算建筑外立面的风雨荷载对于湿气损伤风险评估至关重要。以加拿大渥太华的国会大厦为研究对象，进行了WDR的计算流体动力学(CFD)模拟。结合对当地长期气象条件的统计分析，确定了接收最高WDR量的立面区域。然后，对于立面上的关键位置，考虑到总湿负荷和总干燥潜力，使用气候指数作为度量标准，以确定立面位置和时间，显示出水分破坏的高风险。

Wind-driven rain exposure and moisture damage risk of heritage facades

Accurate estimation of wind-driven rain (WDR) load on building facades is of paramount importance for the assessment of moisture-induced damage risks. Computational fluid dynamics (CFD) simulations of WDR are performed for the Parliament Buildings in Ottawa, Canada. Combined with a statistical analysis of the long-term local meteorological conditions, zones of facades receiving the highest amount of WDR are determined. Then, for critical locations on the facade, the Climatic Index is used as a metric, taking into account the total wetting load and total drying potential, in order to identify the façade locations and periods that show high risk of moisture damage.
