SYNOPSIS

Steel strutted Temporary Earth Retaining System (TERS) is probably the most common shoring support method for deep excavation. Therefore, good understanding of fundamental structural steel design in association with imposed loadings from geotechnical analysis is a key to successful implementation in deep excavation projects. Yet, merely understanding the structural steel design is inadequate to design the steel strutting safely and economically in TERS projects unless appropriate mobilised geotechnical loadings at various construction stages are carefully assessed. In fact, safe and economical design can be achieved when the geotechnical engineer is able to bridge the gap in complicated soil-structure interaction between geotechnical analysis and structural design with practical design considerations. This evening talk will discuss the current common practices by Malaysia’s geotechnical engineers/specialist strutting contractors and the design and construction considerations for steel strutting elements for Klang Valley Mass Rapid Transit (KVMRT) project in Malaysia. The design of steel strutting elements for KVMRT project is in accordance with the limit state design concept in BS5950 and recommendations of CIRIA Special Publication 95 (SP95).


PROFILE OF SPEAKER

Ir. Loh Yee Eng, started TRIGEO Consultant in May 2015 after six years services in G&P Geotechnics Sdn Bhd. She obtained her degree in Bachelor of Civil Engineering from University of Technology Malaysia in year 2000 and Master of Science from the National University of Singapore in year 2007.

Prior to joining G&P in February 2009, she had worked with geotechnical specialist contractors and consultant in Singapore for 9 years, concentrating on the deep excavation, foundation for high-rise buildings and ground improvement. Whilst in G&P, she undertook various projects including the geotechnical design of Platinum Park and The Robertson, geotechnical review of KL118 and Belfield Tunnel, internal checker for temporary works of KV-MRT line 1 and Damansara Uptown project.

Currently, Ir. Loh is a principal for TRIGEO Consultant and provide consultancy services on finite element analysis using PLAXIS and CRISP, foundation design, earth retaining wall design including the design of wall, strutting, ground anchor and ground improvement.
