Axis (4) along the length direction of the building called the longitudinal axis. Its numbering from top to bottom using uppercase letters written in the axis of the circle (where the letters I, O, Z do not).
12. What is the house of the bay, into the deep?
A: The wide bay a house in the distance, and between the two transverse axis; depth refers to the depth of a house in the distance, and two longitudinal axis.

14. What is the total height of the building?
A: The total height of the building refers to the top of the outdoor terrace of the total height of the eaves.
15, what is the elevation? What is the absolute elevation, relative elevation?
A: The height of a part (1) of the building and to determine the reference point of water, known as the parts of the elevation.
(2) the absolute elevation known as altitude, mean sea level of the Yellow Sea near Qingdao as absolute zero elevation, the elevation of the country are as a benchmark.
(3) the relative elevation of the first floor is the main room of the building's interior surface is zero (+0.00), represents the first floor height from the ground somewhere.
16. What is the construction area, the use of space, the utilization rate? What is the transportation area, structure area?
A: (1) the construction of a building area of length, width, size of product outsourcing and multiplied the number of layers. It made use of the area, traffic area and structural composition area.
(2) use of an area refers to the main use of the room and auxiliary use the net area of the room (minus the net area of the axial dimension of the net proceeds thick and the size of the product).
(3) room rate, also known as usage, refers to the use of the area as a percentage of the construction area.
(4) The area is defined as the net area traffic corridors, stairwells, elevators and other transportation links between facilities.
(5) refers to the structure of the wall area, the area occupied by the column.
17, what is the red line?
A: The red line refers to the planning department granted to the construction unit of area, usually circled in red on the drawing, the force of law.
18, how to divide the building rating?
A: The rating is based on building endurance rating (useful life) and fire resistance rating (refractory life) were divided.
(1) Press the durability classification is divided into four levels: more than a durable life of 100 years; two, durable life of 50 to 100 years; three, durable life of 25 to 50 years; four, durable life of 15 years the following.

21. What is the shear wall?
A: refers to the level of shear resistance within the framework of additional shear walls. Due to high-rise buildings to resist horizontal shear is mainly caused by an earthquake, it is also known as seismic shear walls.
22. What is the frame shear wall structure?
A: The frame shear wall structure refers to the vertical load shared by the frame and shear wall; horizontal loads from the frame to withstand 20% to 30%, 70% to shear bear 80% of the structure. Shear length per square meter of 50mm standard design.

Tube structure is dense column frame shear wall or centralized internal and external to the housing to form a closed cylinder space. It features a large shear focused and get free partition space, used for office buildings.
25. What is steel?
A: Steel is the main load-bearing structural components of a building made of steel. With light weight, high strength, good ductility, fast construction, shock resistance and good. Steel used for high-rise buildings, the higher the cost.
26, compared with brick and concrete structure, frame structure what advantages and disadvantages?
Answer:
Advantages: (1) Light weight: weight brick structure of 1500 kg / m; frame structure such as the use of light board (aerated concrete wall, metal frame walls, etc.) of the weight of 400 kg to 600 kg / m , only 1/3 of the brick structure.
(2) The rooms are flexible: the load-bearing structure of the frame structure for the framework itself, siding only separated from the envelope and effect, and therefore more flexible arrangement.
(3) increasing the effective area: frame structure thinner wall than the brick and concrete structure, the relative increase in the housing area.
Disadvantages: (1) steel brick structure than about 30% higher, compared with the brick structure, the high cost.
(2) part of the column cross-sectional size is too large, protruding wall, beautiful affected.

A: (1) the foundation is the basis of the following soil, its role is to bear the entire load of the foundation came.
(2) is based on building buried in the ground below the load-bearing components, is an important part of the building, its role is to bear the entire load of the building passed down, and these, together with the weight of the load transmitted to the soil below.
28. What is the basis of depth? What is the deep foundations, shallow foundations?
A: (1) foundation depth is measured from the floor to the outdoor design basis underside of the vertical distance.
(2) the depth is greater than or equal to 5 meters deep foundation called basis; depth between 0.5 meters to 5 meters foundation called shallow foundation. Foundation depth shallower than 0.5 m not.
29. What are the three basic structures can be classified in different ways?
