腐蚀的结构效应

Share on linkedin Share on facebook Share on twitter Share on telegram Share on whatsapp Share on email Corrosion of steel reinforcement is often investigated in the context of the durability performance of the structure; however, corrosion can equally impact the structural performance. Steel corrosion may result in reduced flexural capacity (loss of rebar cross section), reduced bond, and limited ductility. In this article, we will review some of the…阅读更多 ”腐蚀的结构效应

Major Techniques for Modeling Shear Walls

建模剪力墙建模剪切墙在过去二十年中发生变化。分析技术已经从线性静态移动到非线性动态,从而实现了更现实的建模和仿真。用于建模剪力墙从宏型(如修改的光束柱元件)等剪切墙跨度的不同方法,以微型型号,例如3D有限元模型。适当的建模技术应:能够预测结合重要材料特征的无弹性响应模拟......阅读更多 ”Major Techniques for Modeling Shear Walls

Deficient Shear Walls

缺乏混凝土剪力墙s

Reinforced concrete shear wall structures constructed in the 1970’s or earlier suffer from a number of deficiencies in design and detailing. This is around the time when seismic provisions emerged in the design codes, and changed the traditional strength-based design philosophy (EVOLUTION OF DESIGN CODES). In this article, we will briefly review common problems with deficient concrete shear walls. The focus will be on concrete frame structures, with and without shear…阅读更多 ”缺乏混凝土剪力墙s

What is Ground Penetrating Radar

What is Ground Penetrating Radar

地面穿透雷达(GPR) provides a cost-effective, nondestructive and reliable tool for scanning and imaging of sub-surface defects, voids, and objects. GPR was primarily developed and used in geophysics and geology for subsurface scanning and imaging. Since then, the method has been successfully adapted in many other disciplines including civil engineering. The multipurpose nature of ground penetrating radar and its broad range of applications, make it distinct from existing NDT…阅读更多 ”What is Ground Penetrating Radar

IOT - Intelligent Bridge Monitoring

Intelligent Bridge Monitoring

Have you ever imagined what would happen if highway bridges could speak?: “That I broke an arm? That I have a steel tendon ruptured? …” Well, they are not too far anymore. Last week, I had the chance to participate in a presentation by Jacques Cartier and Champlain Bridges Incorporated (JCCBI) in the GTA, and learned about this smart instrumentation for stress/strain monitoring installed bridge girders. This helped bridge owners…阅读更多 ”Intelligent Bridge Monitoring

Numerical Modeling and Structural Evaluation

Modeling Existing Shear Walls

Modeling existing shear walls can be quite challenging. The first question to ask is how far we want to go – and how much we want to spend on- when it comes to modeling a wall structure. The modeling can be as simple as a beam-columns element, or as complex as a nonlinear 3D finite element model. The design and detailing of reinforced concrete shear walls is a straight forward…阅读更多 ”Modeling Existing Shear Walls
