摘要
桥梁是货物和人员顺利流通的保障。在地震多发地区,桥梁的抗震性能至关重要,尤其是那些具有独特几何形状的桥梁,如零倾斜角的 T 型梁桥。本项目全面分析了倾斜角为 10⁰ 至 50⁰ 的 T 型梁桥。T 型梁桥对不同倾斜角的响应是结构工程学的一个重要研究领域,因为由于几何和场地限制,倾斜桥梁已成为现代基础设施的标准配置。本研究调查了不同倾斜角对 T 梁桥结构性能的影响,重点关注弯矩、剪力、挠度和应力分布等参数。研究利用有限元分析和经验数据揭示了倾斜角的增加如何影响 T 型梁桥的承载能力和变形行为。研究包括几个关键方面:详细记录所考虑的 T 型梁桥的几何形状、所用材料和施工技术,并开发有限元模型以准确表示 T 型梁桥,通过改变倾斜角和应用各种地震地面运动记录进行比较,以模拟桥梁在地震引起的荷载下的响应,并使用力矩、剪切和扭转水平等性能指标评估桥梁的性能。
Bridges are ensuring the smooth flow of goods and people. The seismic performance of bridges, especially those with unique geometries, such as T-beam bridges with zero skew angles, is paramount in earthquake-prone regions. This project comprehensively analyses a T-beam bridge with a 10⁰ to 50⁰ skew angle. The response of T-beam bridges to varying skew angles is a critical area of study in structural engineering, as skewed bridges are standard in modern infrastructure due to geometric and site constraints. This research investigates the impact of different skew angles on the structural performance of T-beam bridges, focusing on parameters such as bending moments, shear forces, deflections, and stress distribution. The study uses finite element analysis and empirical data to reveal how increasing skew angles affect T-beam bridges' load-carrying capacity and deformation behaviour. The study encompasses several key aspects: Detailed documentation of the bridge's geometry, materials used, and construction techniques employed in the T-beam Bridge under consideration and the development of a finite element model to represent the T-beam Bridge accurately, comparison by varying the skew angles and applying various seismic ground motion records to simulate the bridge's response under earthquake-induced loading and assess the bridge's performance using performance metrics such as moment, shear and torsion levels.
