Ecole Polytechnique of Montreal houses the largest structural engineering laboratory in Canada and one of the top facilities of this type in the world. Large scale testing of critical components of building, bridge an dam structures are performed to better understand their behaviour under service loads up to complete failure under ultimate loading conditions. Several test programs are also carried out to evaluate the response of innovative structural systems proposed to enhance the structural performance and durability of infrastructures. Proper assessment of structural response requires an accurate and reliable measurement of the deformations and strains experienced by the test specimens. Test results are also used to verify and calibrate numerical models that are used to complement test programs by studying the effects of additional parameters or assess the performance of entire structural systems. These numerical simulations must precisely reproduce the deformations, strains, and cracks that progressively take place when the structure approaches failure, and high quality experimental data is therefore essential to develop and properly verify numerical models.

蒙特利尔理工学院拥有加拿大最大的结构工程实验室，也是世界上同类设施中最顶尖的实验室之一。对建筑、桥梁和大坝结构的关键部件进行大规模测试，以更好地了解它们在使用荷载下的行为，直至最终荷载条件下完全失效。还开展了多个测试项目，以评估旨在提高基础设施结构性能和耐久性的创新结构系统的响应。 正确评估结构响应需要准确可靠地测量测试样本所经历的变形和应变。 测试结果还用于验证和校准数值模型，这些模型用于通过研究附加参数的影响或评估整个结构系统的性能来补充测试程序。这些数值模拟必须精确地再现结构接近失效时逐渐发生的变形、应变和裂纹，因此高质量的实验数据对于开发和正确验证数值模型至关重要。
