Talk deals with various structural systems involved while designing a structure economically.

1. STERLING
ENGINEERING CONSULTANCY SERVICES PVT. LTD.

2. AS A CIVIL / STRUCTURAL ENGINEERS, WE HAVE BIG ROLE IN
VISUALISING VARIOUS ASPECTS OF A PROJECT.
BASED ON THE CLIENT’S REQUIREMENTS, SERVICES
REQUIREMENTS AND THE MUNICIPAL BYLAWS, ARCHITECT
PRODUCES A SCHEME WHICH IN COORDINATION WITH VARIOUS
SERVICES CONSULTANT, STRUCTURAL SYSTEM/S SHALL BE
PREPARED.
THERE ARE MANY TYPES OF STRUCTURES LIKE
INFRASTRUCTURE, INDUSTRIAL, RESIDENTIAL, COMMERCIAL,
SPORTS FACILITIES, LARGE SPAN STRUCTURES.

ENGINEERING CONSULTANCY SERVICES PVT. LTD.

5. WE WILL BE COVERING MAINLY RESIDENTIAL AND COMMERCIAL
BUILDINGS (THIS PRESENTATION IS BASED ON STRUCTURAL SYSTEMS
ADOPTED IN EXECUTING MANY PROJECTS BY OUR TEAM IN SOUTH
INDIA). ANY SYSTEM PROPOSED SHALL BE VISUALISED WITH THE
FOLLOWING CONSIDERATION.
1. PROPER LOAD FLOW FROM HORIZONTAL PLANE TO ELEMENTS IN
VERTICAL PLANE AND REACHING THE GROUND WHICH ULTIMATELY
BEARS THE LOAD.
2. LATERAL LOADS SUCH AS WIND AND EARTHQUAKE
3. THERMAL LOAD - IF BUILDING IS MORE THAN 40 METERS i.e. ONE
PLAN DIMENSION TO AVOID MOVEMENT JOINTS.
4. SAFETY AND SERVICEABILITY OF THE BUILDING
5. CODE COMPLIANT
STERLING
ENGINEERING CONSULTANCY SERVICES PVT. LTD.

6. ANY SYSTEM SUGGESTED SHALL BE VISUALISED IN COMPLETE BEFORE IT
IS PUT IN FRONT OF CLIENTS. OUR VISIALISATION OF THE BEHAVIOUR
OF EACH COMPONENT OF STRUCTURE, ITS CAPACITY TO RESIST AND
TRANSFER TO THE NEXT ELEMENT AND SO ON.
WE SHALL ALWAYS BEAR IN OUR MIND THAT THE CONTINUOUS
BEHAVIOUR IS VISIALIZED TILL THE LOAD REACHES THE GROUND.

ENGINEERING CONSULTANCY SERVICES PVT. LTD.

7. VARIOUS STRUCTURAL ELEMENTS.
1. SLAB IS A PRIMARY MEMBER WHICH TAKES THE LOADS COMING ON
HORIZONTAL PLANES.
2. BEAMS, WALLS, COLUMNS ARE THE MEMBERS WHICH RECEIVES THE
LOAD FROM SLAB, ITS OWN LOADS AND IMPOSED LOADS AND
TRANSFER TO THE GROUND.
3. IF IT IS MULTI STORIED, THEN COLUMNS AND WALLS WILL TRANSFER
TO THE FLOORS BELOW AND FINALLY TO GROUND.
4. CARE SHALL BE EXCERCISED WHILE DESIGNING EACH ELEMENTS
CAPACITY AND ITS CONNECTIVITY WITH THE SYSTEM.
5. ALWAYS CODAL PROVISIONS SUCH AS THICKNESS, SPAN RATIO SHALL
BE KEPT IN MIND IN OBTAINING VARIOUS SIZES OF ELEMENTS
INITIALLY AND MAY BE REVIEWED DEPENDING ON ARCHITECTURAL
OR OTHER CONSIDERATION SUCH AS SERVICES REQUIREMENTS.

8. THUS, A STRUCTURAL SYSTEM CAN BE DEFINED AS
AN ASSEMBLY OF VARIOUS LOAD TRANSFERRING
STRUCTURAL ELEMENTS TO PROVIDE STABILITY AND
DURABILITY AGAINST LOADS (GRAVITY + LATERAL)
ACTING ON THE SYSTEM.
STERLING
ENGINEERING CONSULTANCY SERVICES PVT. LTD.

9. LOADS
GRAVITY LOADS:
• FLOOR FINISHES
• WALLS / ENCLOSURES
• ANY ADDITIONAL LOADS EXPECTED
• LIVE LOAD AS DEFINED IN IS FOR VARIOUS USES AND ANY SPECIFIC
LOADS FROM CLIENTS OR END USER
• SNOW LOADS IN VERY COLD CLIMATIC CONDITION
• LATERAL LOADS – WIND AND EARTHQUAKE
• SPECIAL LOADS LIKE THERMAL LOADS, BLAST LOADS, IMPACT
LOADS, SETTLEMENT LOADS ETC.
STERLING
ENGINEERING CONSULTANCY SERVICES PVT. LTD.

10. RESIDENTIAL PROJECTS:
DEPENDING ON THE SIZE OF THE PROJECT, EVALUATION OF STRUCTURAL
SYSTEMS HAVE TO BE VISUALIZED. CARRYING OUT PRELIMINARY
ANALYSIS AND SYSTEMS NEEDS TO BE SUGGESTED. ALL SYSTEM
SUGGESTED SHALL BE CODE COMPLIANT INCLUDING SERVICIABILITY,
SAFE & STABLE, ECONOMICAL, CONSTRUTABLE, REPETATIVE USE OF
FORMWORK.
STERLING
ENGINEERING CONSULTANCY SERVICES PVT. LTD.

11. STRUCTURAL SYSTEMS USED IN RESIDENTIAL BUILDINGS ARE,
1. LOAD BEARING STRUCTURE, IN MASONARY WALLS OR REINFORCED
MASONARY WALLS FORMS LOAD TRANSFERING MECHANISM TO THE
GROUND.
2. MOMENT RESTRICTING FRAMES OUT OF COLUMNS, WALLS AND
BEAMS.
3. FRAMED STRUCTURE WITH SHEAR WALLS – SHEAR WALLS WILL HELP
IN CONTROLLING LATERAL DEFLECTION BY RESISTING LATERAL
FORCES.
4. STRUCTURAL WALL SYSTEM IN WHICH ALL WALLS ARE CONSIDERED
AS STRUCTURE AND ANALYSED.
5. DUAL SYSTEM – BUILDING WITH STUCTURAL WALLS AND MOMENT
RESISTING FRAMES

28. STRUCTURAL WALL SYSTEM:
WHEN THE PROJECT IS VERY LARGE, TALL AND REPETITIVE OR NEAR
REPETITIVE, TIME BOUND DELIVERABLES, WE NEED TO THINK OF A
STRUCTURAL SYSTEM WHICH COULD BE FAST IN CONSTRUCTION WITH
MOST OF THE SERVICES COULD BE EMBEDED OR PREPLANNED.
IN THIS, ALL ARCHITECTURAL WALLS WITH CILL LEVEL, LINTEL LEVEL
KNOWN OR DETERMINED ARCHITECTURAL FEATURES. A STRUCTURAL
PLAN USING THESE INFORMATION WILL BE PREPARED WHERE ALL OR
MOST OF THE WALLS ARE USED AS STRUCTURAL WALLS AND ANALYSIS
TO BE CARRIED OUT TO CHECK THE STABILITY. IN MOST OF THE CASES
SINCE THE STIFNESS OF STRUCUTRE IS HIGH, LATERAL DEFLECTIONS
WILL BE USUALLY SAFE.

29. • IN ORDER TO CONSTRUCT, WE NEED THE FORMWORK UNITIZED AND
ASSEMBLED LIKE JIGSAW PUZZLE WITH DETAILED DRAWING AND
PROPER NUMBERING. THIS WILL BE PREPARED BY THE FORMWORK
VENDOR. THERE WILL BE 2 SETS OF DRAWING, ONE FOR THE WALLS
& THE OTHER FOR THE SLAB SUPPORTING SYSTEM. MAJORITY OF
THIS WILL BE FROM STANDARD SIZES WITH NON STANDARD.
• AS OF NOW THERE ARE LARGE NO OF TO PRODUCE THESE TYPE OF
FORMWORKS IN DIFFERENT MATERIALS LIKE ALUMINIUM (WHICH IS
VERY POPULAR), PVC ETC. CONCRETING OF WALLS AND SLAB SHALL
BE POURED TOGETHER IN SINGLE POUR.
STERLING
ENGINEERING CONSULTANCY SERVICES PVT. LTD.

30. • PROPER CONCRETE WHICH CAN FLOW INTO THE WALLS SUCH AS
SMART DYNAMIC CONCRETE AND OR SELF COMPACTING FREE FLOW
CONCRETE.
• IF THE CAR PARKING IS BELOW THE TOWER BLOCK, THEN THERE WILL
BE TRANSFER SYSTEM WITH TRANSFER GIRDER ABOVE CAR PARKING
ZONE. SERVICES INTERFACE NEEDS TO BE EXCERSIZED BEFORE
FINALIZING.
• UPFRONT INVESTMENT ON THE FORMWORK WILL ALSO NEEDS TO BE
EVALUATED AND ITS REUSABILITY.

39. ADVANTAGES:
• PROJECT OF ANY SIZE – LARGE, MEDIUM OR SMALL
• MOST OF THE PROJECTS CAN BE EXECUTED BY MANY VENDORS
• COST EFFECTIVE
• FORMWORK NEEDS TO BE TAILOR MADE FOR EACH PROJECT
EXCEPT STEEL PLATE IF USED FOR SLAB AND BEAM SIDES.
CARE SHALL BE EXERCISED WHILE PREPARING COMPUTER MODEL
FOR ANALYSIS LIKE CONNECTIVITY OF ELEMENTS, LOADS AND UNITS
OF LOADS.
NORMALLY WE DO A SELF WEIGHT CHECK AS SOON AS A FLOOR
PLATE IS READY IN THE MODEL TO CHECK THE CONNECTIVITY AND
DEFLECTION SHAPE OF THE FLOORS. THIS ELIMINATES REDOING
ONCE A 3D MODEL IS CREATED.

40. • ANOTHER ALTERNATIVE WILLL BE THE CORE IN LIFT AND STAIRWELL
AND PERIPHERAL WALLS WITH OPENING. IN PRE-ENGINEERED
FORMWORK WITH INTERNAL STRUCTURAL SYSTEM WITH COLUMN
AND BEAMS OR FLAT SLAB SHALL BE USED. THIS GIVES LOT OF
FLEXIBILITY IN USAGES IF REQUIRED. THESE CAN BE USED FOR ANY
TALL STRUCTURE AS WELL. WE HAVE USED IN BANGALORE OF 37
FLOORS AND IN MUMBAI 50 FLOORS BUILDINGS.

43. • ON A VERY LARGE REPETITIVE OR NEAR REPETITIVE, PRECAST
CONSTRUCTION CAN BE USED. IN THIS ALL THE SLAB PANELS ARE
CAST IN FILGERY SYSTEM, ALL WALL PANELS ARE PRECAST AS PER
DRAWINGS ASSEMBLED USING LARGE CAPACITY CRANES AND FLOOR
SLAB IS CAST IN-SITU TO ACT DIAPHARM IN TRANSFERRING LATERAL
LOADS.
• A HUGE CAPACITY WITH LARGE INVESTMENTS IN SETTING UP PLANT
AND CRANES OF HIGHER CAPACITY ALSO NEEDS KEPT IN MIND.
• IT HAS A LIMITATION ON HEIGHT OF THE BUILDING BECAUSE OF
LOGISTIC ISSUES LIKE LARGE CAPACITY CRANES AND SAFETY IN THE
MIND.

44. COMMERCIAL PROJECTS
STERLING
ENGINEERING CONSULTANCY SERVICES PVT. LTD.

45. COMMERCIAL PROJECTS:
MOSTLY THESE BUILDING REQUIRE LARGE SPAN WHICH ARE GOVERNED
BY CAR PARKING IN THE BASEMENT. DEPENDING ON GRIDS, FLAT SLAB
SYSTEM IS GENERALLY ADOPTED WHICH ARE AS FOLLOWS.
• FLAT SLAB WITH DROP PANEL
• FLAT SLAB WITH COLUMN CAPITAL
• FLAT PLATE (MOSTLY IN RESIDENTIAL PROJECT)
IN A FLAT SLAB SYSTEM, WE HAVE SHEAR WALL TAKING 100% SHEAR
AND PERIPHERY BAND BEAMS CONNECTING COLUMNS WHICH ARE
DESIGNED TO RESIST 25% OF SHEAR INDEPENDENTLY.
SLAB DOES NOT PARTICIPATE IN TRANSFER OF SHEAR TO COLUMN /
WALL.
STERLING
ENGINEERING CONSULTANCY SERVICES PVT. LTD.

46. COMMERCIAL PROJECTS:
• VIODED SLAB – REDUCES SELF WEIGHT AND HENCE REDUCES
SECTION THICKNES REQUIRED.
• POST TENSION SLAB – WHEN LARGE SPAN ARE REQUIRED TO KEEP
THE SECTIONS SLEEK, PT IS REQUIRED.
• GRID / WAFFLE SLAB

69. STRUCTURAL STEEL:
NORMALLY FOR TALL COMMERCIAL BUILDING WITH LARGE SPANS, THE
SELF WEIGHT OF THE STRUCTURE BECOMES VERY LARGE AND EVEN
WITH HIGH GRADE OF CONCRETE, THE SIZE OF THE COLUMNS BECOMES
VERY LARGE AND OCCUPIES THE FLOOR PLATE. IN SUCH SITUATIONS
USING STRUCTURAL STEEL FABRICATED WITH FLOOR AS DECK AND
CONCRETE WITH FIBER REINFORCEMENT / REINFORCEMENT WITH
MESH OR STEEL WILL BE USED AS SLAB.
THIS WILL RESTING ON SECONDARY STEEL MEMBERS WHICH INTURN
ON MAIN STEEL GIDER (CAN BE CASTELLATED ALSO) LAID TO CONNECT
COLUMNS WHICH ARE IN STEEL ENCASED IN CONCRETE TO ACHIEVE
ECONOMY & FIRE PROTECTION OF COLUMNS.

70. STRUCTURAL STEEL:
THE LATERAL LOADS ARE TO BE TAKEN 100% BY THE CORE WHICH
COULD BE STAIRWELL AND LIFT CORE. MOST OF THE JOINTS ARE IN
SHEAR CONNECTIONS AND SOME MOMENT CONNECTIONS ALSO.
THIS SYSTEM IS CHOSEN ON TALL BUILDINGS HAVING LARGE SPANS,
FASTER CONSTRUCTION AND MOSTLY EXTERNAL FINISHES WITH FAÇADE
IN GLASS ON ALUMINUM FIRE RATED COMPOSITE PANELS.

PRECAST WITH IN-SITU JUNCTION CONCRETING.
SLAB IS PRE TENSION HOLLOW CORE SLAB WITH PROPER CAMBER AND
IN-SITU SCREED CONCRETE TO ACT AS DIAPHARM.

78. I take the vision which comes from dreams
and apply the magic of science and mathematics,
adding the heritage of my profession
and my knowledge of nature's materials
to create a design.
I organize the efforts and skills of my fellow workers
employing the capital of the thrifty
and the products of many industries,
and together we work toward our goal
undaunted by hazards and obstacles.
And when we have completed our task
all can see
that the dreams and plans have materialized
for the comfort and welfare of all.
I am an Engineer
I serve mankind
by making dreams come true.
