deck composite steel-reinforced concrete piers reinforced concrete Materials

This project quite complex:• large water depth (up to 65 m) • deep soil strata of weak alluviums• a strong seismic activity• possible tectonic movements

Concept

• Hanger• Pepsi bottele• Sprinlke system• Chimney

1 Logic

• Silty clay -liqufiction-

• Quick sand condition—Japan earthquake

• Concept used – Vital grass root (7m long)

2. Logic

Topling • Each pier moves freely

3. Logic

• Deck movement in earthquake zoneDeck free to moveViscus damfer- control the movement Control the movement – Sprinkling –(60-68*C)Pepsi bottel

4.Logic

• Cables 1997- wind effect Chimney – helical strips

SILT CLAY SOLUTIONLIQUIFICATION

USE THE NEW CONCEPT & DEVELOP
