SELECTING STRUCTURAL SOLUTIONS1.1 Main structure Frame systemThis system is created from vertical bars (columns) connecting with horizontal bars (beams), called “node”. The plane frames are connected to each other in order to make a space frame. In order to increase the horizontal rigidity of frame, braces are added at some span along its height. This component works as a horizontal rigid wall.Advantages: Construction method is simple. This system has large space, flexible plan, and meets all using requirement of the building.Disadvantages: The horizontal rigidity of frame is small, so that horizontal load bearing capacity is low. The beams have big depth that affects to using function and increases the building’s height. Frame system is suitable for low rise building (less than 20 stories for reinforced concrete frame)Bearing wall system In this kind of structure, plane walls are the main bearing elements. In building where walls are installed in one direction, the stability of building in perpendicular direction is ensured by rigid walls. For high rise building, horizontal load is big so that the wall plates are designed to bear all horizontal and vertical loads. The horizontal load is transferred to wall plates through slab system that is absolutely considered as rigidity in its plane. Therefore, rigid walls work as continuous beams with high depth of section. Advantages: By using wall system we can remove the concentration of stress at beamcolumn connection. This system will have torsional rigidity if the walls are connected to each other. It also has great horizontal load bearing capacity, so that this system is suitable for building requiring partition space (house, hotel…).Disadvantages: Using space is limited by walls. The walls has high weight, high rigidity so that the effect of earthquake is big. The buildings will be wall system is commonly less than 20 stories.Framecore system Rigid walls are connected to each other to form a closed (or open) space frame, call “core”. Core has blank box in shape and receives loads then transfers them to earth. Most of the inner space is used for vertical transportation equipment (lift, staircase), technical pipe system (water pipe, electrical pipe). The main advantage of this system is its high bearing capacity of horizontal load and high torsional rigidity. The core works as a big continuous beam fixed to foundation1.2 Slab structure system For building, slab system has big effect on the working of structure. Select structure method is very important. Therefore, we must a proper analysis to choose the method which is suitable for building.Slabrib system Consist of beam system and slabAdvantages: Simple calculation. Used popular in Vietnam, because of structure technology plentiful.Disadvantages: The height of beam and the deflection of slab are very big. Therefore the height of building must be big. That is not saving for cost of materials. not saving space.Mass slab system with four ribs Consist of vertical beam system which divides slabs to smaller slabs with 4 ribs.Advantages: Decreasing the number of column inside the building. Therefore, that saves using space and makes the architecture of building more beautifully. The structure is suitable for the building which is required the high level of aesthetic and big using space .Disadvantages: Not saving, complicated construction. When the area of floor too large, we need to arrange more main beam. Thus, the disadvantage is big height of beam. Slab without beam:Advantages: The height of structure elements is small. Thus, that decreasing the height of building. Saving using space. Easy to divide space. Easy to arrange water and electric technology system. Suitable for building which has medium. Construction of the method is faster than beamslab method, because of not be taking time by reinforcing formwork, reinforcing steel of beam. Because, the height of beams decreases, vertical transportation decreases and cost of construction decreases. Horizontal load decreases, because of the height of building decreases.Disadvantages: The column is not connective. Thus stiffness of frame is smaller than “slab without beam” method. Therefore, horizontal load is loaded by rigid wall. The thickness of slab is big to ensuring the bending resistance ability and antipuncture ability. Thus, the weight of slab is big.1.3 ConclusionBecause, construction is high building which has the big distance between columns. Moreover, to ensure the aesthetic of building, I choose main structure method of building: Pile structure for foundation. Mass slab structure with four ribs. Main structure of building is framecore frame. They create a grid system which support for slab. Rigid walls and columns is buckling to foundation system.2.

- When the area of floor too large, we need to arrange more main beam Thus,the disadvantage is big height of beam

Slab without beam:

Advantages:

- The height of structure elements is small Thus, that decreasing the height ofbuilding

- Saving using space

- Easy to divide space

- Easy to arrange water and electric technology system

- Suitable for building which has medium

- Construction of the method is faster than beam-slab method, because of not

be taking time by reinforcing formwork, reinforcing steel of beam

- Because, the height of beams decreases, vertical transportation decreases andcost of construction decreases

- Horizontal load decreases, because of the height of building decreases

- Pile structure for foundation

- Mass slab structure with four ribs

2 DETERMINATION OF PRELIMINARY DIMENSION OF ELEMENTS 2.1 Material

- Concrete grade B25: Rb= 14,5 MPa; Rbt = 1,05 Mpa; Eb =3.0x103 MPa

- Steel :

+ Φ < 10 mm: Steel AI: Rs = Rsc = 225MPa

+ Φ ≥ 10 mm: Steel AII: Rs = Rsc = 280MPa

+ Steel AIII: Rs = Rsc = 365 MPa

2.2 Preliminary dimension of elements

2.2.1 Thickness of slab

- Choose beam and slab floor solution is arranged through column and use

secondary beam

- Choosing the thickness of slab based on the formula :

Legend:

+ D= 0.8-1.4: loading factor

+ m : Factor of edge supported slabs

m = 35-45 : two way slab

m = 30-35 : one way slab

+ L1: Shorter span of slab

With slab has the largest dimension (4.2m x 7.8m)

D= 1.2 : loading factor

M= 45: Factor of edge supported slabs ( two way slab)

L1=3.9 : Shorter span of slab

hs = 420 = 11.2 cm > hmin = 5 cm

Choose the thickness of slab : hs = 12 cm

- The dimension of beam cross section based on experience formula:

Legend:

 =8-12: with primary beam

 =12-16: with secondary beam

 L: Length of beam span

Choose the height of beam : hd = 55 cm

Dimension of beam : bd x hd = 22x55 cm

 Other secondary beams ( shorter span)

Choose dimension of beam : 22x40 cm

The demension of the column is preliminarily choosed by fomular :

Legend :

A : cross-section area of column

k : Affected factor by moment, k = 1-1,5

Rb : Compressed strength of concrete

N: Axial force caused by vertical loads N=S.q.n

In which :

+ S : Bearing load area of a column in a storey + q : Preliminary load q= 12KN/m2 = 1.2x10-2 Mpa + n : Number of storeys

- Bearing load area S= ( + )x4.2=22.05 m2

- Assuming all the live loads on the floor are 300 daN/m2

TT Load Unit (daN)

- Bearing load area S= 3,9x4,2=16,38 m2

TT Load Unit (daN)

- t≥1/20.ht = 1/20.3500 = 175 ( ht is height of one storey)

Choose the thickness of shear wall is 220 mm

1.3 Wind load

- Wind has become a very important load in recent years due to the extensive use

of lighter materials and more efficient building techniques A building builtwith heavy masonry, timber tiled roof may not be affected by the wind load,but on the other hand the structural design of a modern light gauge steel framedbuilding is dominated by the wind load, which will affect its strength, stabilityand serviceability The wind acts both on the main structure and on theindividual cladding units The structure has to be braced to resist the horizontalload and anchored to the ground to prevent the whole building from beingblown away, if the dead weight of the building is not sufficient to hold it down.The cladding has to be securely fixed to prevent the wind from ripping it awayfrom the structure

- Following TCVN 2737-1995 Royal Hotel is located in Hanoi, so it has W0=95KG/m2 and in II-B zone

- The hight of the building is lower than 40m, so we only need to consider thestatic wind load

- Design wind pressure applying on 1m2 of vertical surface is ditermined thefollowing formula :
