<strong>Structural</strong> <strong>for</strong>ms suitable <strong>for</strong> build<strong>in</strong>gs <strong>in</strong> HK<br />
7. Composite structure (RC Core plus steel frame, hybrid<br />
structure)<br />
- build<strong>in</strong>g can be lighter than usual RC structure but<br />
with a more acceptable rigidity than pure steel<br />
build<strong>in</strong>gs<br />
- construction cost is higher <strong>for</strong> the add<strong>in</strong>g <strong>in</strong> of a RC<br />
core which requires a complicated <strong>for</strong>mwork system<br />
- it is time consum<strong>in</strong>g and more complicated to make<br />
connections between the RC and steel elements<br />
- It is even more difficult and costly if stiffen<strong>in</strong>g<br />
members are <strong>in</strong>troduced <strong>in</strong>to the build<strong>in</strong>g <strong>in</strong> order to<br />
make it more rigid to resist deflection<br />
- Build<strong>in</strong>g examples: Time square, Manual Life Tower,<br />
Cheung <strong>Kong</strong> Center, IFC 1 and 2
