  • 1. POST-LINTEL STRUCTURE
  • 2. STRUCTURAL METHOD POST-LINTEL STRUCTURE POST-SLAB STRUCTURE WALL SLAB STRUCTURE STEEL STRUCTURE COMPOSITE STRUCTURE
  • 3. POST & LINTEL Simple form of construction involving posts carrying horizontal beams or lintels, as in timber- framed work or in columnar and trabeated architecture. Ancient Egyptian and Ancient Greek architecture was of this type, using stone. Stonehenge is an example of post and lintel construction
  • 4. Structural Shapes Structural Shapes, Roofing, and Framing
  • 5. POST & LINTEL SYSTEM  Post Lintel is a Frame structure  Use of Concrete Materials, Mixing of aggregate, gravel, sand, Cement with water.  It may be lightweight or heavy weight structure.  Mixing ratio: 1:2:4, 1:3:6 & 1:1.5:3 etc  In more recent time it has been found possible to produce steels. According to many codes & specifications such as 80ksi, 60ksi, & 40ksi etc.  60ksi steel is most commonly used.
  • 6. FOUNDATION The foundation is the part of a structure that is usually placed below the surface of the ground & that transmits the load to the underlying soil or rock.
  • 7. FOUNDATION TYPE  Footing • Wall Footing - R.C Wall - Masonry Wall • Column Footing - Rectangular - Square •Combined Footing  Pile  Mat, Raft or Deep Foundation

  • 9. COLUMN A column is a vertical support structure. According to ACI Code : Rectangular column _ Minimum 96 in² or 8’’X12”, steel 4 bars, Tie 3/8’’ dia or ½’’ dia. Spiral column – Minimum 100 in² , 10’’ dia steel 6 bars, Tie 3/8’’ dia , Not exceed than 3’’ & less than 1’’ Circular Column 10'' 10''10'' 10'' 8'' 12'' Rectangular Column Square Column
  • 10. ECONOMICAL COLUMN SPAN COLUMN SIZE Column size not less than 10“x10” for ACI code 15'-0" to 21'-0" depends on ground floor perking & drive way BEAMCOLUMN(POST-LINTEL)STRUCTURE COLUMN SPAN & SIZE
  • 11. DOUBLE HEIGHT COLUMN THICKNESS POST-LINTESTRUCTURE Double height column depends on slender test of column or effective length of column buckling For member with h/t up to 10 (approximately h/r up to 35) For column with h/t = 20 (approximately h/r up to 70) R became 0.07 Team roll of dabble height column thickness, If column length is upward for axial load then column section is enlarge for a column.
  • 12. BEAM The beam is a very sturdy structure. A beam is a horizontal pole. It is usually shaped as a rectangle so there is more balance between the poles. A beam is held up by one or two columns. If there are two columns, they are placed on either side of the beam. If there is one column, it is placed in the middle of the beam so each side is balanced. Beams are found in many places - in buildings, in homes, and in moving structures.
  • 13. DISTRIBUTION LOADS POST-LINTESTRUCTURE Distributed Load DISSTRIBUTED LOAD SECTION OF BEAM Concentreted Load SECTION OF BEAM Concentrated Load
  • 14. BEAM TYPES According to Reinforcement there are two types of beam : Single reinforcement beam Reinforcement bar are used in the tensile zone. Double reinforcement beam Reinforcement bar are used in the tensile & Compression zone. SINGLE REINFORCEMENT BEAM SECTION DOUBLE REINFORCEMENT BEAM SECTION
  • 15. BEAM TYPES According to Support there are four types of beam : Simply Supported Beam One end Continuous Supported Beam BEAMCOLUMN(POST-LINTEL)STRUCTURE
  • 16. BEAM TYPES  Both end Continuous Supported Beam  Cantilever Beam BEAMCOLUMN(POST-LINTEL)STRUCTURE
  • 17. Clear span of column & the beam thickness is convert to inches for column span length. For an example column span clear 20’-0” so for this region beam thickness 20” for this span BEAMCOLUMN(POST-LINTEL)STRUCTURE 20’ Column Span 12” 20” BEAM THICKNESS
  • 18. Structural Joint Joint of Beam & Column Beam Column
  • 19. ECONOMICAL CANTILEVER PORTION POST-LINTESTRUCTURE we use to cantilever not less then 5’-0” for open side on a support. But its depends on overturning moment should be balance by type of load or embedded layer.
  • 20. POST-LINTE STRUCTURE SLAB POST-LINTESTRUCTURE SLAB There are two type of slab use in post lintel structural system One-way slab A one-way slab is essentially a rectangular beam of comparative large ratio of width depth. And steel use to short direction of slab. One Way Reinforcement Slab 20'-0" 45'-0" Botomwithalt.Ckd. 10mmØ@6"C/CStd.
  • 21. POST-LINTE STRUCTURE SLAB POST-LINTESTRUCTURE Two way slab Most rectangular reinforced concrete slab are supported on all four side by beam , girders or walls. 20'-0" 20'-0" Botom with alt.Ckd. 10 mm Ø @ 6" C/C Std.

POST-LINTE STRUCTURE SLAB POST-LINTESTRUCTURE SLAB THICKNESS we are use to thump roll of structural system for slab thickness T = Parameter 180 For example for a slab T = 2 X (ax b) x 12 180 Minimum slab thickness for ACI code a) Simply Supported L / 20 b) One end continuous L / 24 c) Both end continuous L / 28 d) Cantilever L / 10

  • 28. POST-LINTE ADVANTAGES POST-LINTESTRUCTURE AESTHETICS Aesthetically this structural system seems quite sound by using the expression of post-lintel structure in the exterior facades. Sometimes the heavy or rigid masses are treated politely by using the framework of the post-lintel which gives an extra ordinary looks. SPAN & SPACE Larger span (column to column distance) of building is possible to design in this system. For the large span the lintel height become larger for this a large space seems small, as the lacking of clear height. Sometimes this problem creates visual disturbance, which is avoided, in flat slab.
  • 29. POST-LINTE ADVANTAGES POST-LINTESTRUCTURE ECONOMIC The construction cost of this system is slightly high for the time consuming casting of beam and slab and the use of R.C.C. The maintenance cost of this system remains lower than the other structural system for its long lasting characteristics. CLIMATE Considering the climate this system is more suitable for our country. The admission of heat become reduced in this system, as the heat transferred from the slab to beam and then from the beam to floor. The control of openings admits the little amount of heat in the building. For the free flowing plan light and ventilation can easily insert the building.
  • 30. POST-LINTE ADVANTAGES POST-LINTESTRUCTURE ENVIRONMENT This structural system having less self-loads which reduces the risk of danger of earth quack. It can resist the buckling or bending effect of the building from the strong wind flow. It has the capability of fire resistance for the construction material (R.C.C.). So this system is very much suiting with respect to our environment. CONSTRUCTION TECHNICS In this structural system construction process takes a long time for the casting of beam and slab because at first column and beam cast and after that the slab cast. High cost materials are used in this system. In post-lintel system ducting process is not so easier compared to Post-slab.
  • 31. POST-LINTE ADVANTAGES POST-LINTESTRUCTURE OPENNINGS In post-lintel system 50% area of the external facade is remaining for the openings of the building. For this there is a control over use of openings. The admass of light and ventilation is smaller compared to post-slab. SUSTAINABILITY Sustainability means the ultimate capacity of individual members and as well as the whole structure against any types of overloading such as cyclones, earth quacks, etc. Sustainability of structures may also termed as factor of safety because overloading is allowed only up to the safety level which was taken in considering at the time of design. Stability of any structure is the critical point of failure. If stability is not satisfied it limits the values, then the failure may come suddenly. This system has less possibility of failure than the other structural system.
  • 32. POST-LINTE ADVANTAGES POST-LINTESTRUCTURE FLOOR SLAB Floor slab is a slab supported on ground generally distribute load to the ground uniformly. It also increases the bearing capacity of soil as the load distributes combined. SOLID-VOID RATIO By using the framework of post-lintel system we can make a sense full solid-void ratio which illuminate the monotonous effect. CANTILEVER OR OVERHANG The portion of any structure that is over hanged without any support termed as cantilever. Sometimes cantilever construction is economical and looks aesthetically attractive which may become a useful part of that structure.
  • 33. Limitation  Extreme variation of solid & is not possible.  Opening should be place considering the post.  Stair must start with respect to a beam.  Building height increases for the beam to get clear Space.  Also duct for air conditioning are used under beam, so floor height increases which is not acceptable for height.  This system more costly (30%more)than wall slab system.  But economic range can be kept in a lower gird when the span is limited 15’ to 25’.  Uninterrupted vast space can not be created without using vault dome or waffle.
