Construction Stage Analysis of a Metro Station

Overview

In this tutorial the modeling

sequence for a 2D metro station has

been given.

The figure on the right shows the

cross section of the metro station.

The ground has 9 different layers of

soil

Four different stages of excavation

have been id entified.

L1- Ground to Roof Slab

L2- Roof Slab to Ticket Slab

L3 Ticket Slab to In termediate Sl ab

L4 Intermediate Slab to Raft Slab

The columns, barrets, slabs and D

wall have been mod eled as

structural elements (beam elements).

On the next p age a zoom ed in view

of the D wall and columns can be

seen.

Note: 1. D Wall conc rete is used in D Wall and B arrets2. Structural Concrete is used in Slabs and Columns

GTS provides two types of materials, Ground and Structural. Ground is used to define material characteristics for those elements which are used to represent soil/ground (like plane strain in 2D and so lid elements in 3D).Structural material is used to define the material characteristics of struc tural elements like beam/truss/plate etc,

Procedure

1. The table on the right shows all

the Attributes created for

different soils.

2. Upper Clay Drained and Lower

Clay Drained have been defined

separately because their

properties are diff erent during

drained and undrained behavior.

3. So the Drained behavior of Claywil l be simulated later on as a

boundary condition during the

modeling process.

4. In the next step we create the

At tr ibutes for the Structural

connectivity it is necessary to

intersect those edges which are

in contact (like Wall and slab

are in contact so the edges

representing them need to be

intersected)
