Structural floor system was selected as the floor structure without beams (also known as floor Flat Slabs phang- mushrooms or floor) no column caps.
There are 2 methods of calculating and defining moment in the floor structure was put into two regulations of the United States, Australia and some European countries are Au.Do direct design approach and the equivalent frame method.
However, in today's reality, the computer was used very popular in offices design consultants and engineers doing design work in the field of construction. With the software calculates the current structure, the structural problems in 3D space can be solved by finite element method is no longer a big problem anymore. Therefore, the design method on only meaningful when appropriate reasoning and calculations manually cong.Trong this project, the method used is to use software to find internal resources Safe v12.2 slab.
the floor boxes have holes arranged technical systems such as water supply and drainage pipes ... cross floor, still regarded as continuous. Later, we will use structural measures to handle.
The floor structure is also flat floor structures bending under 2 attacks. If the system has structural beams supporting the floor 2 on 4 sides, the whole load on the ground are passed on to the floor beams, the flat, the load on the ground will be transmitted to the strip located under the colonnade floor and this band called the column strips (similar to the structural beams in the floor beam system).
in practical design, the floor is divided into strips on poles and strips midspan. Strips on the floor of the column is located on the strip width columns get beat on each side by a quarter from the heart of every column shaft. Midspan strips are strips are formed from a border between two columns of two strips. See the column on the working range as continuous beams on the top of the column list, but the range between rhythm is also continuous strip onto the pillow Statistics elastic bands on the column is perpendicular to divide the strip no.So map calculated as follows (including 11 horizontal and 7 vertical strips strips)
