Structural analysis of a buidling using Robot Structural Analysis

1) What are HVAC systems? Why are they essential in the modeling of buildings

HVAC stands for heating, ventilation and air conditioning. It is technology of indoor environmental comfort. It's goals is to provide thermal comfort and acceptable indoor air quality.

HVAC system design is a sub discipline of mechanical engineering based on the principle of thermodynamics, Fluid Mechanics and heat transfer

It is an important part of residential structure such a single-family home, Apartment buildings, hotels and senior living facilities, medium to large industrial and office building such as skyscrapers and hospitals were safety and health it building condition are regulated with respect to temperature and humidity using  fresh air from outdoors.

HVAC system for essential in modelling of building because :

They used for controlling the overall climate of the building this means that when it is the warm outside it balances the temperature to make the inside more cooler and while it is winter season it will make warmer. The air conditioner work during the warmer days while the boilers and heaters are turned on during the colder days

HVAC fosters in enhanced productivity in offices as they feel comfortable and when they are comfortable, the mind and body tends to function better, leading them to deliver the best job result.

It improves the quality in the building making it appropriate for human breathing and comfort. It reduces humidity so that the residents can enjoy a better atmosphere, hence this is useful in building and underground spaces where the ventilation is limited.

It helps you achieve more savings when it comes to energy bills. In olden days where we used fans and old schooled-air conditioner and fire places to keep us warm or cold had many limitations but now the advancement in the technology has made things much more easier by making everything automatic and thus reduces the energy consumption.

2)From week 7 assignment, based on the building designed use the same Revit file to design a HVAC system for each floor to cover the topics included in the class.
            a. Typical HVAC unit includes Distribution center
            b. Collector
            c. Ducts
            d. Blower
Based on the layout choose appropriate ducts and elevation using property browser and assign the components to appropriate groups to complete modeling of the HVAC unit

Aim:

To design HVAC system for each floor that includes:

A) Distribution  centre

B) Collector

C) Ducts

D) Blower

Procedure:

i) Initially open the architectural template previously created.

ii)Then, go to the system tab and in that choose air terminal and load the elements like the supply diffuser.

iii) First choose the supply diffuser and place it conveniently.

iv) Now similarly choose return diffuser and place it appropriately.

v) Next we have to provide ducts.

vi) For this, initially select the return diffusers and AHU unit and then click on duct.

vii)Then generate the layout desired. Similarly, create the duct for supply diffusers.

viii) Hence the system is developed the for level 1 and  similarly create the system  for level 2 and level 3.

3)

AIM:

To load plug-ins for robot structural analysis to Revit software using the add-ins tab.

PROCEDURE:

RESULT:

The robot structural analysis tool kit has been successfully loaded.

Structural analysis is essential in modelling element as it helps in calculating and determining the effect of loads and the internal force on a structure, building or an object. It is particularly important for structural engineers to ensure that they completely understand the load paths and impact of the loads in their engineering design. It allows engineer or designer to ensure that a piece of equipment or structure is safe for use under the estimated load, it is expected to withstand.

Structural analysis can either be performed during design testing or post construction and will generally account for material used, geometry of the structure and applied loads. Structural analysis usually look at individual structural elements and forces they undergo. Structural engineer will look at structural analysis result for beams, slaps, cables and walls. All this element have force applied to them such as windload, liveload and deadload. So it is important for aengineer to review how each of these element behave under the loads, this is the core focus of structural analysis.

The structural design does affect the modelling. It will help to design the better models and covers the issues with an existing model and allows to incorporate the alternatives.

Aim:

To carry out structural analysis using robot structural analysis.

Procedure:

a) Boundary conditions:

It is a place on structure where either the external force or the displacements are known at the start of analysis. For a structural analysis problem tool be solve, every location on the boundary of structure must have known force or a known displacement. The known force or displacement may have some magnitude or it may be zero. For example, if there are location in the structures that have no external force, this would be zero boundary condition. A displacement boundary that is zero is equal to the structure of being held in place at that location.

b) The loads that must be applied to floorings are:

c)

Aim:

To list the load combination and include them in the analysis model

Procedure:

1) Initially open the week 7 assignment in the structural template and open the analytical model.

2) Then click on the manage tab and go to structural settings.

3) Now, structural setting dialogue box opens.

4) In this we have to set the load combination.

5) Now, we have to set the boundary condition.

6) For this, go to analyse tab, in that choose thd boundary condition amd provide the state as fixed.

7) Hence the boundary conditions are defined.

8) Now, again go to analyse tab and choose loads and provide the loads.

9) Now we have to proceed to analysis.

10) For this, go to the analysis tab and select robot structural analysis.

11) Click on robot structural analysis.

12) The model is then opened in Robot structural analysis.

13) The model is opened in robot structural analysis.

14) Go to analysis ----> loads ----> automatic loads.

15) Loads will be automatically applied

16) Now, go to the analysis and run the calculation.

17) description of reaction is provided above.

E)Yes, the analysis of the model has given the better approach in the modelling structural members.

Result

Hence, the analysis is completed.

Energy analysis :

It is a traditional method of accessing the way they energy is used in an operation in moline the physical and chemical processing of material and transfer and conservation of energy.

Energy usage analysis involves for principal steps :

1. Calculation of heat loss and gain to the buildings spaces and the heating and cooling loads imposed upon the building systems.

2. Calculation of energy addition and extraction to meet the possibly varying temperature set point and humidity criteria.

3. Determination of fuel requirement of primary equipmentsin the attempt to supply the energy demand of ventilation system.

4. It evaluates cost of equipments, fuels, electricity, labour and retrofit components against the alternate of investing money in other way.

Energy stimulation can help in analysing the movement of energy in and out and through the rooms and volumes in the building models. This information can help the designer make better informed cost-effective decisions that improve the performance and reduce the environmental impact of the building.

Whole building energy simulation measures expected energy use ( fuel and electricity) based on the building geometry, climate type and building type, envelope properties and active system, it takes into account the interdependency of building as a whole system.

A sustainable energy design is intended to be completely eliminate all the negative environmental expect through the thoughtful design. This concept can be applied across all field of design like designing buildings. A sustainable design, regardless of application will seek to incorporate environmentally preferable outcomes such as :
