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. For all North American engineers, you can also join our next sessions by signing up here www.midasoft.com/midas-expert-network.

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.

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.

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.

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.

Designing a curved bridge was a challenge for me in every aspect. The tendon profile in MIDAS Civil, which we covered before, it’s a very well-known issue,

1. Introduction

In India, the IS codes, or Indian Standards codes, play a crucial role in ensuring the quality, safety, and reliability of structures in India. It serves as an essential benchmarks to guide the design, construction, modification, and upkeep of structures. These codes are formulated by the Bureau of Indian Standards (BIS), a national body that develops and publishes standards to promote quality and consistency across various industries. These codes are reviewed from time to time and updated to reflect the latest developments in industries.
