STRUCTURAL DESIGN AND DETAILING OF ONE STORIED...

STRUCTURAL DESIGN AND DETAILING OF ONE STORIED HOUSE

STEPS TO FOLLOW

From the provided architectural plan you can

have the dimensions of beams, columns and

slabs

Develop framing plan

Mark Grids, like A, B, C along the x-axis and 1, 2, 3

along the y-axis

Mark all the beams as B1, B2, B3, B4 and so on

Mark Columns as C1, C2, C3, C4 and so on

Develop elevation view for the structural

elements in the building

MARK THE GRIDS

Sample grid marking

Design the slabs as per ACI (13.5.1.1) and

calculate loads using ASCE 7 and the load

combinations in Table 1.2 of ACI 318.

CLASS ASSIGNMENT Design the following one storied house.

DESIGN OF TWO WAY SLABS (REVISION)

Use Direct Design Method DDM to design the

slabs

ACI Code (13.5.1.1) specifies the design

procedure

Revise chapter 16 of “Design of reinforced

concrete by J.C. McCormac” to follow the steps

SLAB THICKNESS

Assume 40 psf live load for residential usage.

Determine the thickness of all slabs, and assign

the maximum calculated thickness to all of the

slabs for similarity in design.

DESIGN OF BEAMS

HOW TO TRANSFER LOAD FROM SLABS TO THE BEAMS

REFER TO BOARD LECTURES

DESIGN OF BEAMS

Design beams using section 4.2 of chapter 4

“Design of reinforced concrete by J.C.

McCormac & R. H. Brown”

Draw beam profiles for typical beams and draw

their sections

DESIGN OF COLUMNS

HOW TO TRANSFER LOAD FROM BEAMS TO THE COLUMNS

Use Moment Distribution Method MDM to

transfer the moments and loads from the beams

to the columns.

REFER TO BOARD LECTURE FOR FURTHER

DETAILS

DESIGN OF COLUMNS

Refer to chapter 9 of “Design of reinforced

concrete by J.C. McCormac & R. H. Brown”

DESIGN OF FOOTINGS / FOUNDATIONS

DESIGN OF FOOTINGS

Refer to chapter 12 of “Design of reinforced

concrete by J.C. McCormac & R. H. Brown”

Complete the structural drawings with footing

and foundation details
