Case Study Webinar How Close Are We to The Reality? May 24, 2022 (Tuesday)

Modelling using Midas GTS NX - how close are we to the reality? – Sharing of two project applications

Project application 1: Concrete infilled steel pipe pile – load-settlement curve

Project application 2: Failure of a RC pile supported RC wall in soft clay


The finite element is sought after by practicing engineers to solve unconventional problems. In bridge foundation design, structural engineers may want to increase the rigidity of the steel pipe pile by infilling the steel pipe pile. This is unconventional to the typical steel pipe pile analysis. Midas GTS NX was employed to simulate the load-settlement curve of the concrete infilled steel pipe pile and typical steel pipe pile. On the second project application, leakage from the swimming pool built on the RC wall has caused the water to build up behind the RC wall and subsequently triggered the failure. Midas GTS NX was employed to uncover the whole failure mechanism.

Ong Yin Hoe


Ir. Dr. Ong Yin Hoe has a Masters in soil engineering from Asian Institute of Technology (AIT) and Doctor of Philosophy in civil engineering from Universiti Teknologi Petronas (UTP). He has worked as a geotechnical engineer for 20 years including as resident engineer for foundation works, anchored contiguous bored pile wall, diaphragm walls, bored piles and jack – in piles. He has also been involved in the design of highways on soft ground. As well he has vast experience in three dimensional finite element analysis of tunnels, basement excavations and bored piles and has been involved in impact assessment of basement excavations on existing tunnels, underground rail stations and existing viaduct structures. He has authored of more than 10 papers on numerical methods and bored piles.
