Understanding Eurocode 1:

Actions on Structures and the Role of Basic Wind Velocity Data

 

🌬️ "Why Was Finding Wind Data Always Such a Hassle?"

 

Whenever I applied wind loads during structural design, I’d find myself hauling out a hefty tome standard manual that could double as a doorstop and squinting at tiny, barely readable maps, trying to pinpoint my project location. For familiar regions, this was manageable, but for less familiar places, it often turned into a frustrating guessing game, especially when manuals offered nothing but pages of cryptic tables instead of clear maps. I’d waste valuable time double-checking, second-guessing, and wondering if I had the right data. That’s why we created the Basic Wind Velocity Map—a digital tool designed to make retrieving wind speed values quick, intuitive, and frustration-free. No more flipping through outdated manuals or wrestling with static maps; this tool ensures you can instantly access accurate wind data, focus on what matters most, and design confidently. 🚀

🚀 Why Bother Drawing a Response Spectrum Manually?

 

We usually rely on the response spectrum data generated by our software. However, you'll manually open Excel to create a custom spectrum when a project has specific requirements. The reference peak ground acceleration (PGA) didn't match standard values, or additional factors must be applied for uncommon site conditions or design scenarios.

I've been there, too. Even when the project does not explicitly require it, I often encourage my team to draw a response spectrum manually. For seismic design engineers, understanding the relationship between a structure's natural period and ground acceleration isn't just helpful—it's essential. Whether you're analyzing general structures or ground models using EN1998-1 or designing bridges according to EN1998-2, mastering this concept is the foundation of effectively working with Eurocode 8.

🕖 Surviving in times of change

 

I felt one thing while working as a structural engineer who designs concrete bridges(RC/PSC) according to various countries' design standards: A profound understanding of ACI318(AASHTO) and EN2 is essential to successfully working on bridge projects. Most countries' standards are developed based on those standards. (Of course, it is my personal opinion.) Personally, I believe that my design career was successful because I recognized these facts.

 

 Reviewing the ACI318 and EN once is not enough because design standards change over time. Revision is an indispensable process, and I expect two things before the new edition is released.

 

 First, to be precise, the existing vague parts; the other is simplifying the calculating equations to apply the practical design process. Fundamentally, those are relevant problems. Complexity usually brings unclear parts.

 Unfortunately, the newly updated 2G:Eurocode 2 did not meet these expectations. Standards are more convoluted than before, and this has indeed led to an increase in unclear areas.

 

 Now, the moment has come to prepare for the future.

⚙️ Introduction to Our New Tool

 

Now, let's talk about tools.

The primary function of this tool is to easily output stress-strain curve graphs, which are strength characteristics of concrete, and graphs of time-dependent characteristics such as creep and drying shrinkage.

 Notably, by providing the existing EN1992-1-1 and the new 2G:EN1992-1-1 together, the user can compare those results and experience the calculating processes. I believe it would be a handy tool to validate that new standards align with user understanding before implementing them in practice.

Some people have already heard about the second generation of Eurocodes. It’s not too early to figure out what changes are in the second generation and what civil and architecture engineers need to know. This blog does not handle the specifications; however, it would be helpful for those who want to know the overall changes. I will give you a quick summary for busy people.

What is Application Programming Interface (API)?

 

The first thought that will come into your mind is exactly what is this API? and why a civil engineer like me needs to know about this techno-sounding topic.

In this webinar, Top MIDAS Expert Yanling Leng from IMEG present on the advances and technology trends in bridge inspection, load rating, and design that could impact the bridge industry. She also shared her thoughts on how technological advances impact the value of bridge engineers??skills. Our team collaborated with her to demonstrate the capabilities of midas CIM.

Defining Suspension Bridges: An Engineering Marvel

Suspension bridges are remarkable structures supported by massive main cables stretched between two or more towers. This design is the preferred choice for expansive spans where conventional bridge types prove impractical. The main cables, anchored at both ends of the bridge, are under tension and bear the weight of the bridge deck along with dynamic loads from vehicles and pedestrians. Typically, the deck hangs below these main cables, secured by smaller vertical cables or rods.

 

Beam Bridges: An Essential Element in Transportation Infrastructure

Beam bridges, commonly referred to as girder bridges, represent one of the most prevalent and fundamental bridge types globally. Despite their apparent simplicity, these structures play a pivotal role in our transportation systems, ensuring the safe passage of vehicles and pedestrians across various terrains such as rivers, valleys, and highways. This article delves into the design, construction, and essential features of beam bridges, highlighting the science behind their stability and strength.

 

1. Introduction

When performing the Rail-Structure Interaction (RSI), It is often found that the stress limits are exceeding the permissible values. So there are some countermeasures to ensure safety. Let’s look at how we can implement these control measures which affect the stresses in rails when performing rail structure interaction.

👉🏻 Check out our previous post

1. Introduction

With the recent development of high-speed trains globally, structural interaction plays an important role in estimating the impact of rail on the bridge and the optimum design of the bridge system for the safe passage of trains without disturbing the passengers' riding comfort. The UIC 774-3, Eurocode in 1991-2, RDSO, Korean code, ACI, and various codes and standards provide methodologies for considering rail-bridge interaction problems in the design and analysis of railway bridges. These guidelines take into account the dynamic interactions between trains and bridges, which can affect the stress, displacement, and stability of the rail during train passage. Based on experimental and numerical studies, these guidelines provide limiting values for stress, displacement, and stability of the rail to ensure railway bridges' safe and reliable performance. These limiting values are derived to prevent excessive deformations and stress in the rail that could lead to failure of the rail or other bridge components.

Introduction to MIDAS Connector

The newly to be released MIDAS CIVIL NX has an API feature installed. API stands for Application Programming Interface, which is a language used for communication between the operating system and applications. In other words, a communication environment has been set up where you can send or receive data from MIDAS CIVIL NX through the API. However, to utilize the API, you need to know how to code using a development language. It feels like there's more to do because you need to know how to code.

1. Introduction

In Prestressed concrete structures, the prestressing force is a crucial variable type. The behaviors of pre-stressed concrete structures depend on the effective prestress because it provides compressive stresses to counteract the tensile stresses that develop in the concrete due to loads. However, the prestressing force does not remain constant over time due to various factors that cause prestress losses. These losses can occur during the transfer of prestress from the tendons to the concrete member or over the service life of the structure.
