Spanning the Impossible: The Art and Science of Suspension Bridges

MIDASoftJuly 25, 2024

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.

Rail Structure Interaction Verification as per UIC 774-3 - Part 2

midasBridge TeamJune 5, 2024

 

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.

Rail Structure Interaction Verification as per UIC 774-3 - Part 1

midasBridge TeamMay 24, 2024

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.

MIDAS Connector: Revolutionizing Data Exchange with MIDAS CIVIL NX

midasBridge TeamMay 17, 2024

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.

Prestress Tension Loss Verification as per EN 1992

midasBridge TeamMay 10, 2024

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.

The Reality: Difficulty in Integrating Classroom Learning into Practical Design

Recent surveys indicate that 78% of civil engineering graduates in the United States felt that what they learned in school didn't translate well into practical application. Why is there such a disparity between academia and real-world practice? The primary reason is that while universities predominantly focus on 2D-based mechanics, practical design involves considering various load combinations and complex structures.

The Impact of Differential Shrinkage

midasBridge TeamApril 25, 2024

A. Introduction:

Differential shrinkage is a phenomenon that occurs in composite sections, which are made up of different materials or different grades of concrete, as the different materials will experience a different rate of shrinkage (i.e., PSC composite I Girder). In this article, we will focus on differential shrinkage due to the different time-dependent effects for the composite section consisting of the same material with different grades of concrete for the deck slab and the girder. Differential shrinkage is an important concept to consider when designing composite sections even when the same material is used for both the girder and deck, the age difference will cause the differential shrinkage effects. This will induce different time-dependent effects on both since both the parts are integrally connected internal stress will be generated to reduce the differential effect.

[API] Temperature Gradient Self-Equilibrating Stress Calculator

midasBridge TeamApril 11, 2024

1. Why do bridge engineers consider Non-linear Temperature Gradients?

Temperature loads threaten bridge safety, especially for long-span bridges. If the bridge is located with a big temperature difference, A structural engineer analyzes and designs a bridge based on the beam theory. The temperature gradient should be considered with the beam theory. The beam theory assumes the beam deforms primarily in one direction, the material behaves linearly elastic, and the beam has a uniform cross-section. It means even if the beam cross-section gets a different thermal expansion depending on the depth, the cross-section does not change, and it is also possible to substitute thermal stress as a self-equilibrating stress in restraint conditions.
