The Importance of Soil-Structure Interaction in midas Civil

1. MIDAS Open API (Application Program Interface) Workflow

API (Application Programming Interface) is a type of software that provides a connection between computers or between computer programs. Furthermore, API helps interface within the software. There are often misunderstandings of why an engineer wants to implement API. First of all, rather than focusing on the value of the API, it is better to think about the value of the effect it brings. APIs make sense when they provide a channel through which businesses can access the current value in new ways.

Dynamic Analysis of Fan, Semi-Fan, and Harp Type of Cable-Stayed Bridges

While modeling cable-stayed bridges, the different types of cable arrangements such as Fan, Semi-Fan, and Harp type is often considered. Since they vary in cable arrangement, the pretension in the cables is different and the deflection, bending moment, and stresses vary in the bridge. It then becomes prudent to choose the best arrangement for a more optimized design leading to lesser cost and increased safety.

In this article, we present, in a concise way, the modeling of a Cable-Stayed Bridge in midas civil with three different cable arrangements. Furthermore, Response Spectrum analysis is carried out on the models to study the Dynamic Responses of the three arrangements.

Meshing

As structural engineers, whenever we need to analyze a complex structure, we turn to FEM (Finite Element Method) analysis for a quick solution with acceptable accuracy. The generalized beam element model is quite sufficient in most cases; however, there are a few instances in which we may need to go for detailed 3D finite element analysis. Few such cases are joint analysis, buckling analysis, material non-linear analysis, and so on. But hey, meshing even matters in simple linear analysis! Let’s have a look at the basic guidelines for meshing and the process of mesh convergence.

Elongations of Prestressing Steels

 When we build prestressed concrete structural members, which is a frequently used material for bridges worldwide, the benefit in material savings and reduction of dimensions is guaranteed only when it is built correctly. Structures behave the way they are built, and not the way they are designed, so it is imperative that the designer and reviewer engineers provide the necessary information so that the construction process is oriented towards a structure that meets all safety requirements.
