Structural analysis of a buidling using Robot Structural Analysis
1) What are HVAC systems? Why are they essential in the modeling of buildings
HVAC SYSTEM STANDS FOR HEATING, VENTILATION AND AIR CONDITIONING. IN HEATING THEIR IS INCRESE IN TEMPERATUTRE.
IN VENTILATION THE OLD AIR IS REPLACED BY THE NEW AIR AND IN AIR CONDITIONING COOL AIR HEKPS TO REDUCE THE TEMPERATURE.
IT HELPS TO MOVE THE AIR BETWEEN INDDORS AND OUTDOORS. IT IS USED IN BOTH RESIDENTIAL AND COPMMERCUAL BUILDINGS
HVAC HAS THE MAIN OBJECTIVE AS TO PROVIDE COMFORT.
THE HVAC WORKS AS IT FIRST SOURCES A FRESH AIR INTAKAE FROM OUTSIDE OR FROM HOME WITHIN IN CASE OF VENTILATION
FOR COOLINS AND HEATING IT IS AN ARTIFIACL PROCESS WHERE IN HEATERS AND AIR CONDITONERS ARE PROVIDED.
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 PROVIDE HVAC SYSTEM FROM WEEK 7 PROJECT
PROCEDURE-
OPEN REVIT SOFTWARE
CLICK ON NEW AND THEN CLICK ON MECHANICAL TEMPELATE
SAVE THE PROJECT
THE CLICK ON INSERT AND LINK THE WEEK 7 FILE
NOW CLICK ON SYSTEM TAB AND THEN CLICK ON AIR TERMINAL
THEN SELECT SUPPLY DIFFUSER AND PLACE THE SUPPLY DIFFUSER WHERE REQUIRED.
NOW CLICK ON SYSTEM TAB AND THEN CLICK ON AIR TERMINAL
THEN SELECT SUPPLY DIFFUSER AND PLACE THE SUPPLY DIFFUSER WHERE REQUIRED AND REPEAT THE PROCCES SEVERAL TIMES
THEN SELEC T ALL THE SUPPLY DIFFRENT AND AIR HANDELLING
GO TO MODIFY TRAB AND CLICK ON DUCTS CLICK OK
CREATE THE MECHANIOCAL SIPPLY AIR SELKCT LAYOUT
NOW SELECT THE SYSTEM AND COPY IT TO ALL THE LEVELS
3) Use the add-ins tab to load plug-ins for robot structural analysis to your Revit software
AIM- TO ADD THE ROBOT STUCTURE TO REVIT SOFTWARE
PROCRDURE-
GO TO AUTODESK WEBSITE
SEARCH THE ROBOT STRUCTURAL ANALYSIS PROFESSIONAL
INSTAAL THE SETUP FILE
RESTART THE PC OR LAPI
THE OPEN THE REVIT SOFTWARE
CLICK ON NEW FILE
GO TO ANALYSE TAB TO THE ROBOT STRUCTURAL ANALYSIS PROFESSIONAL
4) Why do we need to assess buildings/analyze while modeling elements? Does design affect modeling in anyways?
Structure is one of the important component of building
The structural framework is the skeleton to the building
All ther losds and load transfer is taken care by creating the structural framework
analyzing a building is nothing but calculatiing forces and bending moments that occur when loads are applied
revit enables us to calulate the forces reactions bending moments that occur when loads are applied
analysis option making the work of the designer easy
the result of the analysis are used to verify a stuctures fitness for use often precluding physical test 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?
AIM- TO EXPORT THE COMPLETE ANALYTICAL MODEL TO ROBOT STRUCTURAL ANALYSIS
PROCEDURE-
OPEN REVIT SOFTWARE
OPEN THE STRUTURAL MODEL PF WEEK 7 PROJECT
GO TO PROJECT BROWSER
AND CLICK ON ANALYTICAL MODEL
GO TO ANALYSE TAB AND SELECT LOAD OPTION
TAKE THE REQUIRED LOAD CONDITIONS THEN APPLY THE LOAD CONDITON
SELECT THE LOAD THEN CHANGE THE LOAD PARAMETRS
SLECT THE LOAD AND COPY IT AND THEN PASTE TO ALIGNED LEVELS
GO TO ANALYSE TAB AND SELECT LOAD OPTION
TAKE THE REQUIRED LOAD CONDITIONS THEN APPLY THE LOAD CONDITON
GO TO ANALYZE TAB THEN CLICK ON LAOD COMBINATIONS THEN NAME THE LOAD COMBINATIONS
CLICK ON ADD AND AND EDIT THE SEKECTED FORMULA
THEN CLICK ON TIMES AND THEN ON LAODS AND THEN SELCT THE FACTORED VALUE
REPEAT THE PROCEDURE OF LOAD COMBINATIONS
GO TO ANALYSE TAB CLICK ON RORBOT STRUTURAL LINK AND THEN CLICK OK
OPEN THE MODEL IN ROBOT STRUCTURAL ANAYLSIS SOFTWARE
NOW GO TO LOAD TAB SELECT THE AUTOMATIC COMBINATIONS THEN CLICK OK AND THEN SET THE LOAD COMBINATIONS
GO TO ANALYSIS TAB SELCET THE ANALYSIS TYPE THERN CLICK ON CALCULATE TO COMPUTE THE STRUTURAL CALCULATIONS
NOW GO TO RESULT TAB CLCIK ON DAIGRAM AND BARS
TICK THE DESCRIPTION BOX
MOMENT REACTIONS RESULT FOR DEAD AND LIVE LOAD
SUPPORT REACTIONS RESULT FOR DEAD AND LIVE LOADS
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 traditional method of assessing the way energy is used in an ioperation invovling the physical or chemical peocessing of materails and the transfer or conversion of energy
energy usage analysis of the buildings involves four principalsteps.
first is the calculation of the heatioss and gain to the building spaces and the heating and cooling koads imposed upon the building HVAC system. this calculations is carried out for space temperature fixed in time ans is commnly called gthe ;oad cazlulations
Sustainable design seeks to reduce negative impacts on the enviroment and the health and comfort of builfing occupants thereby improving building performance. the basic objective od sustainability arer to reduce the consumption of non renewable resources minimize waste and create healthy productive enviroments.
it include the ability to
optimize site potential
minimize non-renewable energy consumption
use enviromentally perferable products
