I hope advices, remarks and suggestions of teachers and all of you.Thank to you sincerely Ha Noi, June2016StudentNGUYEN XUAN TUNG  PART IARCHITECTUREDrawing:•KT01 Elevation of the building.•KT02 Crosssection AA and BB of the building.•KT03 Ground and first floor plan.•KT04 3rd6th floor plan and roof plan. 1.GENERALIn the recent years, Vietnam’s economy has changed dramatically along with the rapid growth of the other countries in Asia. The reconstruction and construction of infrastructure is needed in the open door period. On the other hand, the demand of housing is very necessary to resolve land issues as well as changing the urban landscape to deserve with the stature of a large city.Ha Noi is the capital of Viet Nam. This capital has been center of political, economy, culture, education and entertainment of the country. Ha Noi capital with approximate 6.6 million in population. The land of the city is now depleted while the demand of land for business is increasing. Therefore, the construction of a highrise building that combines both commercial and leasing agencies is essential and appropriate to deal with those above issues. Because of these reasons, the “CT2 Apartment” is licensed to build. Figure I.1.

Layout reasonable apartments, to ensure sanitation, facilitate transportation and living.Architectural requirements: to aesthetic and consistend with the trend of social development. Consistend with the overall architecture of the building of new urban and local air. Take full advantage of ventilation and natural lighting, to ensure facilitate transportation, quick and safe escape and timely for people when the incident occurred.Design building include the basement to keep the car, the other floor layout household room, on the roof layout swimming pool and technical room.Building full layout transportation system in both horizontal and vertical to suited for traffic problems in the building.1.3.Climatic conditionThe building is located on Hoang Mai district, Ha Noi city. In which is typical for the northern climate, is characterized by tropical monsoon climate: hot summers and rainy, dry winters and less rain. Because of its location in the tropical monsoon climate to Hanoi to receive yearround solar radiation is abundant and high temperature. The amount of radiation a total annual average of Hanoi is 122,8kcalcm2 and the average air temperature annual is 23,6oC. Due to the influence of the sea, humidity, the average rainfall is quite large in Hanoi. The average relative humidity is 79% annually, the annual average rainfall is 1245mm per year and an average of 114 rainy days. From May to September is hot and rainy season (1682mm rainfall year), this time is often stormy, wind levels from level 8 to level 10 and sometimes up to level 12. From November to April next years later that is winter, dry weather. There have a transition period between the two seasons (April and October).Hanoi has 4 seasons: Spring, summer, fall, winter. There is sometime freezing temperatures down to the 2,70C (thang1 1955) and is the most intense heat with temperatures up to 42,80C in Hanoi (May 1926).The study area is dominated by the Hanoi climate is considered harsh with high moisture and high humidity, large amplitude, cool northeast monsoon. Beside, the last weather is good, the temperature and humidity in accordance with the average human comfort, cool southeast monsoon. The design architecture is exploited the advange and disadvanges of the weather.1.4.HydrogeologyBase on the Area Geological of Soviet Union (former) recorded at Hanoi Masterplaning Construction Institute, most studied area is located on the 2nd partition geology; is considered favorable level for construction. Structure from top to bottom is silty clay layer (thickness of 57 meters) plastic clay clay hard fightingplastic clay soft clay. A small section in the south lies on the third partition geology is not favorable assessment for construction. When implementing specific projects for geological exploration drilling in the study area to solution processing structure suitable foundation works.2.ARCHITECTUAL BRIEF2.1.Solution for master planning and elevationThe complex form is appartment with 7 floor in the center of project. The cover outer walls were painted and tiled to created special view for the project. Using architecture square columns with groove pattern, doors and windows glass door layout by arch steel frame combined with a balcony used to get light, ventilation and aesthetically created for the project. The combined idea with the medium height, the concrete segments and vintage ornamental pattern is used effectively not only the environment, but also healthy surroundings. The main idea illustrate that the living space is good orientation, environment and can view the scenery outside.The purpose of the project is to create an architecture simple and minimum to optimize the efficiency of land use and environmental conditions.The Serves Area of all the project is the space which combined with landscape garden, to create a master plan with high uniformity and harmony with landscape architecture.Vertical transportation included stair and elevatorProject is a high rise building. Its height is 26.4m with 7 floors, an attic and a roof with elevation: Ground floor elevation : 0.000m. 1st floor elevation: +3.2m. 2nd floor elevation: +6.40m. 3rd floor elevation: +9.60m. 4th floor elevation: +12.8m. 5th floor elevation: +16.0m. 6th floor elevation: +19.20m.

STRUCTURE

 Requirement:

 Structure solution for building

 Determine load cases

 Calculation internal forces and internal forces combination

 Designing frame axis 4 (typical slab, frame, foundation)

 Drawing:

 KC-01- Frame reinforcement from basement to 3rd floor

 KC-02- Frame reinforcement from 4th to roof

 KC-03- Slab reinforcement of typical floor

1 SOLUTION IN STRUCTURE

1.1 Solution for main structure

Basic bearing structure for building

Frame system

This 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 aspace frame

In order to increase the horizontal rigidity of frame, braces are added at some span alongits height This component works as a horizontal rigid wall

Brace framing system

For high rise building, horizontal load is big so that the wall plates are designed to bearall horizontal and vertical loads The horizontal load is transferred to wall plates throughframe and slab system that is absolutely considered as rigidity in its plane Therefore,rigid frame has efficient lateral stiffness so that it can resist lateral loads together withshear walls

Advantages:

By using brace framing system we can remove the concentration of stress at column connection This system will have torsional rigidity if the walls are connected toeach other It also has great horizontal load bearing capacity, so that this system issuitable for building requiring partition space (house, hotel…)

beam-Disadvantages:

Using space is limited by walls so that it can located on elavators pit, staircase andboundary wall

1.1 Solution for floor

To building, slab system has big effect on the working of structure Select structure

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 spaceand makes the architecture of building more beautifully The structure is suitable for thebuilding 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, thedisadvantage 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 beam-slab method, because of not be takingtime by reinforcing formwork, reinforcing steel of beam

Because, the height of beams decreases, vertical transportation decreases and cost ofconstruction decreases

Horizontal load decreases, because of the height of building decreases

The thickness of slab is big to ensuring the bending resistance ability and anti-punctureability Thus, the weight of slab is big.

Pre-stressed slab without beam.

Advantages:

Fix some disadvantages of “slab without beam” method:

Decreasing the thickness of slab and weight of slab Thus, decreasing the horizontal loadand vertical load

Increasing the stiffness of beam

Loading diagram become optimal

Disadvantages:

Designing and construction is complexity

Cost of equipment is high

1.1 Structure selection

The features that directly affect to structural solution of building:

The height of the typical storey is small, just 3.2 m It is needed to pay attention to slabsolution to ensure the clear height

Columns span is nomal (7.0 m in longitudinal and 4.0 m in horizontal) This building isused for living so more brick walls are installed

Lift system is located in the center of the building (in longitudinal direction) combinedwith stairs

Number of storey: 9 Height: 26.4 m

From those above analysis, the CT2 Building seems to be suitable with frame system

structure

With above features, frame and slab without beam is chosen for building structure

1.1 Solution for material

Choosing materials for bearing structure of high rise building must based on thefollowing basic standards:

Materials must have rate between strength and weight as much as possible

High deformability will overcome the low bearing capacity of materials or structure.Low decomposition: those materials are preferred to be used when the building issubjected by repeated load

High monolithism: When vibrating, building shouldn’t separate its components

Reasonable costs: Ahigh bearing capacity building is always connected to reasonable

1.1.1 Reinforced concrete

Advantages:

Nowadays, reinforced concrete is commonly used due to the development of science andtechnology This kind of structure is simply constructed and has common materials,stable to environment Furthermore, we can utilize the high compression of concrete andhigh tension of steel because of their cooperation For high rise building, reinforcedconcrete structure has high reliability about strength and stability

Disadvantages:

Reinforced concrete structure requires big size component, high self weight This causesthe complex choosing solution in structure It is difficult to fit reinforced concretestructure with architecture design

Therefore, based on the above analysis and supply capacity, construction schedule, localmaterials, the CT2 Tenement House (9 stories, 26.4 m high) is suitable with reinforcedconcrete:

Concrete B25: Rb = 145 kG/cm2, Rbt = 10.5 kG/cm2

Rebar type AI: Rs = 2250 kG/cm2 and AII: Rs = 2800 kG/cm2

1.1 Preliminary dimensions of columns

Columns are using concrete grade B25 with Rb=14.5 MPa and Rbt=1.05 MPa

The column dimension is calculated by:
