Construction Stage Analysis

Construction Stage Analysis


A civil structure such as a suspension bridge, cable-stayed bridge, or PSC (prestressed or post-tensioned concrete) bridge requires separate and yet inter-related analyses for the completed structure and interim structures during the construction. The structural behaviors such as deflections and stress re-distribution continue to change during and after the construction due to varying time-dependent properties such as concrete creep, shrinkage, modulus of elasticity (aging), and tendon relaxation. Since the structural configuration continuously changes with different loading and support conditions, and each construction stage affects the subsequent stages, the design of certain structural components may be governed during the construction.

Cable Bridge Special Features

Cable Bridge Special Features


midas Civil is a powerful software that can handle complex bridges including cable bridges. It has specific functions that make the modeling and analysis process accurate and effective so that you can invest your time in checking the results. Unknown Load Factor Use optimization techniques or combine equations to determine the optimal load factors that satisfy the specific constraints of a structure. This function optimizes the tensions of cables at the initial equilibrium position of a cable structure. Suspension Bridge Wizard performs an initial configuration analysis only considering the cable system. Obtain the initial cable force as well as the initial geometry for cable stiffness using this function.

Soil-Structure Interaction


With the use of multiple boundary conditions available in midas civil, simulating the soil properties on your structural model is made simple. Midas Civil provides compression-only, tension-only, and multi-linear spring supports to simulate the soil-structure interaction in the same platform. No more reaction tables and estimations. midas Civil provides compression-only, tension-only, and multi-linear spring supports to simulate the soil-structure interaction in the same platform.

Segmental Bridge Capabilities

Segmental Bridge Capabilities


Segmental bridge construction involves the consideration of different loads, multiple concrete maturities, staged tensioning, long-term effects, stresses checks, etc. Midas Civil can consider all together within one model. Simulating an earthquake during construction, which is also required by different codes, can be easily done in midas Civil. The tendon losses, elongation, weight are easily obtained in tables for fast processing. Midas Civil allows for automatic camber calculation at each construction stage using camber control functions.

Network Tied Arches by Gregor Wollmann at HNTB
Pioneered in the 1960's by Norwegian Engineer Per Tveit, network tied arches offer significant advantages in terms of stiffness, material consumption, and resiliency under extreme loading when compared to traditional tied arches with vertical hangers. The structural system is characterized by two families of longitudinally inclined hangers, such that hangers cross each other to form a network, resulting in a configuration that combines the advantages of arch, truss, and cable stayed bridges.

Spanning Bridges Using Extradosed Cables
This session would cover an excellent example for multi-span extradosed bridge. The discussion would cover topics like construction methodology adopted to reduce the construction duration and economizes the overall cost as well as, construction constraints such as tidal conditions and weather. Also, a brief on how bridge progress till date substantiates the importance of sound efforts in planning, design, and management.

Segmental Construction - Helicoidal Bridge
The Helicoidal Bridge is part of a road with a total of 3.5 kilometers, of which 125 meters are tunnels and 395 meters of the bridge. The bridge is 1296 ft long with a diameter of 590 ft. The bridge is mounted-on friction pendulum seismic isolators that allow the displacement of the superstructure in an earthquake or due to temperature changes.

Complex Bridge
A complex bridge is one of the most common engineering projects nowadays. This category of structures includes movable, cable-stayed, segmental concrete, and other bridges with unusual characteristics. These types of structures will require specialized expertise to design and build. One of our Expert Engineers, Yazeed Abuhassan, a Structural Design Engineer from Bergmann PC, shared his tips about designing a complex bridge.

Introducing To Cable Stayed Bridge Modeling And Analysis
construction analysis to cable tuning force. We will cover using the wizard to model the bridge with ease and then go over how to set up construction stages. The unknown factor function which is used to get a rough cable tuning force will also be explained. Finally, in more depth, the cable tuning force, which can be fixed by the constraints such as moment and displacement so on through a tool, will be demonstrated which is for a real-time application.
