Structural analysis of a buidling using Robot Structural Analysis

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

ANS.

• HVAC STANDS FOR HEATING, VENTILATION AND AIR CONDITIONING.
• IT IS A IMPORTANT PART OF BUILDING MODELLING.
• HEATING MEANS TO INCREASE THE TEMPERATURE OF THE INCOMING AIR IN THE BUILDING.
• VENTILATION IS A PROCESS TO MAINTAIN THE FLOW OF THE FRESH AIR IN THE BUILDING.
• WHILE THERE ARE SEVERAL DIFFERENT TYPES OF HVAC SYSTEM, THEY ALL BEGIN WITH THE SAME ESSENTIALS.
• FIRST. THERE IS A SOURCE OF FRESH AIR INTAKE FROM THE OUTSIDE OR FROM WITH IN THE HOME.
• THIS PROCESS IS CALLED VENTILATION, AND IT HAPPENS IN TWO DIFFERENT WAYS. NATURAL VENTILATION IS PRESENT IN MOST HOMES AND REFERS TO THE WAY AIT TYPICALLY MOVES IN AND OUT THROUGH
• WINDOW, DOORS, VENTS, AND OTUER OPENING. THIS EXCHANGE OF AIR IS NECESSARY TO REPLENISH OXYGEN, AND TO REMOVE ODORS, CARBON DIOXIDE AND EXCESSIVE MOISTURE.
• MECHANICAL VENTILATION USE A MECHANICAL SYSTEM - THE V IN HVAC TO MOVE AIR IN AND OUT.
• IN THE PAST, THERE WAS PLENTY OF NATURAL VENTILATION IN MOST HOMES FROM GAPS AND CRACKS IN THE CONSTRUCTION ALONG WITH OPENING AND CLOSING OF DOORS.
• HOWEVER, MODERN CONSTRUCTION IS CREATING HOMES THAT ARE FER MORE TIGHTLY SEALED SO VENTION IS BECOMING AN INCREASINGLY IMPORTANT COMPONENT IN HOME HVAC SYSTEMS.
• ONCE THE AIR IS BROUGHT IN IT IS DRAWN INTO AN AIR HANDLING UNIT WHERE THE WORK BEGINS. HERE, THE AIR IS BROUGHT IN, IT IS DRAWN INTO AN AIR HANDLING UNIT WHERE THE WORK BEGINS.
• HERE, THE AIR IS DRAWN THROUH FILTERS TO REMOVE DIRT, DUST, ALLERGENS, AND OTHER PARTICLES.
• NEXT UP, IS COMFORT AIR IS EITHER SENT TO BE HEATED OR SENT TO BE COOLED AND HAVE EXCESS HUMIDITY REMOVED. ONCE THE AIR IS CEAN, FRESH, AND AT A COMFORTABLE TEMPERATURE, IT IS DIRECTED INTO HOME. FOR CENTRAL SYSTENS, THIS MEANS MOVING THROUGH A NETWOTK OF DUCTS AND REGISTERS TO DIFFERENT ROOMS. FOR OTHER SYSTEMS, THIS USUALLY MEANS BEING DIRECTED RIGHT INTO THE SPACE.

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.

ANS.

• FOR HVAC DESIGN OPEN THE REVIT THEN SELECT THE MECHANICAL TEMPLATE TO WORK ON.

• NOW GO TO THE INSERT TOOL BAR AND SELECT LINK REVIT OPTION TO LINK THE FILE TO THE MECHANICAL TEMPLATE.

• NOW SELECT THE FILE YOU WANT TO LINK.THEN PRESS OPEN AND THE DESIRED FILE WILL BE OPENED IN THE TAB.

• NOW FOR THE PLACEMENT OF THE MECHANICAL EQUIPMENTS GO TO THE SYSTEMS TOOLBAR AND THEN SELECT THE AIR TERMINALS FOR THE SUPPLIER AND THE RETURNS.

• NOW ADJUST THE SUPPLIER AND RETURNS TO THE CEILING AS NEEDED.

• NOW ADD THE AIR HANDLING UNIT FROM THE (SYSTEM > MECHANICAL EQUIMENT > AIR HANDLING UNIT).

• NOW ADJUST THE AIR HANDLING TO THE AREA AS NEEDED.

• NOW FOR CREATING THE CONNECTIONS SELECT ALL THE SUPPLIERS AND AIR HANDLING UNIT AND THEN SELECT DUCT OPTION TO CREATE CONNECTION .

• NOW DO THE SAME PROCESS FOR THE RETURN VALVES AND HENCE THE HVAC SYSTEM IS CREATED.

----------------------------------------------------------------------------------------------------------------------------------

3) Use the add-ins tab to load plug-ins for robot structural analysis to your Revit software.

ANS.

• FOR THE ROBOT STRUCTURE ANALYSES SOFTWARE GO TO THE ADD-INS TAB .
• NOW AFTER REACHING THE OFFICIAL AUTODESK WEBSITE SEARCH FOR THE ROBOT STRUCTURAL ANALYSIS PROFESSIONAL AND ALSO USE THE COMPATIBLE VERSION OF THE REVIT AS THE REFRENCE.
• NOW INSTALL IT IN YOUR PC.
• HENCE THE ROBOT STRUCTURE ANALYSIS WILL BE AUTOMATICALLY LINKED TO THE REVIT.
• NOW SEE IN THE ANALYSIS TAB TO SEE IF THE ROBOT STRUCTURE ANALYSIS IS LINKED OR NOT.

-----------------------------------------------------------------------------------------------------------------------------------

4) Why do we need to assess buildings/analyze while modeling elements? Does design affect modeling in anyways?

ANS.

• STRUCTURE IS ONE OF THE IMPORTANT COMPONENT OF THE BUILDING.
• THE STRUCUTURAL FRAMEWORK IS THE SKELETON TO THE BUILDING.
• ALL THE LOADS AND LOAD TRANSFER IS TAKEN CARE BY CREATING THE STRUCTURAL FRAMEWORK.
• ANALYZING A BUILDING IS NOTHING BUT CALCULATING FORCES AND BENDING MOMENTS THAT OCCUR WHEN LOADS ARE APPLIED.
• REVIT ENABLES US TO CALCULATE THE FORCES, REACTIONS, BENDING MOMENTS ETC BY USING THE ROBOT STRUCTURAL ANALYSIS OPTION MAKING THE WORK OF A DESIGNER EASY.
• ENERGY ANALYSIS IS ALSO AN IMPORTANT ASPECT AS IT CALCULATES THE OVERALL PERFORMANCE OF BUILDINGS.
• ANALYZING A BUILDING IS VERY IMPORTANT BECAUSE IT GIVES A COMPLETE UNDERSTANDING OF THE BUILDING AND HOW ITACTS WHEN SOME NATURAL CALAMITIES LIKE TORNADOS , EARTHQUAKES OCCUR. ANALYSIS OR ASSESSMENT OF BUILDING MAKES US UNDERSTAND HOW MUCH STRENGH A BUILDING GIVES AND HOW MUCH IS THE ACTUAL REQUIREMENT, THIS HELPS US TO MAKE REQUIRE CHANGES TO ATTAIN THE EPECTED FUNCTIONALITY.
• STRUCTURAL ANALYSIS IS THE DETERMINATION OF THE EFFECTS OF LOADS ON PHYSICAL STRUCTURES AND THEIR COMPONENTS.
• STRUCTURES SUBJECT TO THIS TYPE OF ANALYSIS INCLUDE ALL THAT MUST WITHSTAND LOADS, SUCH AS BUILDING, BRIDGES, AIRCRAFT, AND SHIPS.
• THE STRUCTURAL ANALYSIS EMPLOYS THE FIELDS OF APPLIED MECHANICS, MATERIALS SCIENCE, AND APPLIED MATHEMATICS TO COMPUTE A STRUCTURES DEFORMATIONS, INTERNAL FORCES, STRESSES, SUPPORT RECTIONS, ACCELERATIONS, AND STABILITY.
• THE RESULTS OF THE ANALYSIS ARE USED TO VERIFY A STRUCTURES FITNESS FOR USE, OFTEN PRECLUDING PHYSICAL TESTS. STRUCTURAL ANALYSIS IS THUS A KEY PART OF THE ENGINEERING DESIGN OF STRUCTURES.

5) From the structural model developed in week 6 and 7, export the complete analytical model to robot structural analysis.
a. List your assumptions on what boundary conditions will be realistic for the analysis approach
b. Use the design standards to decide what loads must be applied to floorings based on the type of structure decided
c. List the load combinations and include them in the analysis model
d. Analyze the building and report the following results
i. Maximum Moment in each floor for all Load Combinations
ii. Maximum Displacement in each floor for all Load combinations
iii. Lateral Displacement in building for all Lateral Load combinations
e. After analysis, do you think you have a better approach or idea in modeling structural members?

6) What is energy analysis and why do we need to consider it while modeling in Revit?

How does the factor of sustainability improve the quality of your design?

ANS.

• ENERGY ANALYSIS IS THE TRADITIONALMETHOD OF ASSESSING THE WAY ENERGY IS USED IN AN OPERATION INVOLVING THE PHYSICAL OR CHEMICAL PROCESSING OF MATERIALS AND THE TRANSFER AND CONVERSION OF ENERGY.
• ENERGY USAGE ANALYSIS OF BUILDINGS INVOLVES FOUR PRINCIPALSTEPS.
• FIRST IS THE CALCULATION OF HEAT LOSS AND GAIN TO THE BUILDING SPACES AND THE HEATING AND COOLING LOADS IMPOSED UPON THE BUILDING HVAC SYSTEMS. THIS CALCULATION IS CARRIED OUT FOR A SPACE TEMPERATURE FIXED IN TIME AND IS COMMONLY CALLED THE LOADS CALCULATION.
• SECOND IS THE CALCULATION OF THE ENERGY ADDITION AND EXTRACTION ACTUALLY TO BE SUPPLIED BY THE HVAC SYSTEM IN ORDER TO MEET THE POSSIBLY VARYING TEMPERATURE SET-POINTS AND HUMIDITY CRITERIA SUBJECT TO THE SCHEDULES OF FANS. BOILERS. AND CHILLERS, AND TO OUTSIDE AIR REQUIREMENTS. THIS CALCULATION RESULTS IN THE DEMAND FOR ENERGY THAT IS MADE ONTHE PRIMARY ENERGY SOURCES OF THE BUILDING. THIS STEP.CALLED THE SYSTEMS CA CULATION.
• THE THIRD IS THE DETERMINATION OF THE FUEL REQUIREMENTS OF PRIMARY EQUIPMENT SUCH AS BOILERS AND CHILLERS, AND OF THE ENERGY PRODUCTION OF SOLAR COLLECTORS,ETC..IN THE ATTEMPT TO SUPPLY THE ENERGY DEMAND OF THE HVAC SYSTEMS. THIS PLANT CALCULATION
• THE FOURTH STEP EVALUATES THE COSTS OF EQUIPMENT FUEL ,ELECTRICITY,LABOR AND RETROFIT COMPONENTS AGAINST THE ALTERNATIVE OF INVESTINGTHE MONEY INOTHER WAYS.
• SUSTAINABLE DESIGN SEEKS TO REDUCE NEGATIVE IMPACTS ON THE ENVIRONMENT, AND THE HEALTH AND COMFORT OF BUILDING OCCUPANTS.THEREBY IMPROVING BUILDING PERFORMANCE. THE BASIC OBJECTIVES OF SUSTAINABILITY ARE TO REDUCE THE CONSUMPTION OF NON-RENEWABLE RESOURCES. MINIMIZE WASTE, AND CREATE HEALTHY, PRODUCTIVE ENVIRONMENTS.
