Suggestions from the construction, force, design, maintenance and other aspects of the answer, haste.
There is no obvious shortcomings, may also be able to use the most mature and most widely used high-rise steel structure of the floor form.
The design theory is mature and simple; if you do not consider the combination of the pressure plate of the force (generally so consider, the design of the steel plate, Only the pressure plate as the bottom mold, the design only check the construction phase of the limit state to meet the requirements), the plate under pressure plate specifications, fire requirements, rust requirements are relatively simple.
Must pay attention to the shortcomings, the first, the span of 3m within the general, there is no suitable for the cast plate span; second, the conversion plate thickness is larger, the corresponding load is also larger, the main structure of steel will rise.
Advantages: short construction period, easy on-site operation, building integrity is better than prefabricated floor;
Disadvantages: due to the need for multi-channel trabecular, the floor occupied by a larger height, and pressure plate at the end of the need to do fire treatment.
Compressed steel plate concrete composite floor: the use of concave and convex pressure between the thin plate made of liner and cast-in-place concrete pouring together in the steel beam on the composition of the whole floor, mainly by the floor layer, composite plate and steel beam composed of three parts. Suitable for large space construction and high-rise buildings, has been widely used in the international arena.
