PNS 16

P

hilippine National Standard for C.H.B

AISC-LRFD 99

2] Design Material Strength

fc’ 25 mpa

For all concrete sections without honeycomb and

conformed to 40% by wt. water cement ratio

(Footing,Column,Slab and Beam)

fy 415 mpa For deformed reinforcing bars(for beam B1

450 x 680 ONLY, note use fy 275 mpa for stirrup)

fy 275 mpa

For all deformed reinforcing bars

(Footing,Column,Slab and Beam Rebars)

Note 1: Material strength provided above shall be maintained

in the construction.

Compression testing for concrete and tensile for

steel shall be conducted to maintained structural

stability of the design.

Note 2:

Frame analysis and design results are purely based on

code and material strength mention above.

Data:

Material

Strength:

fc'

=

25 MPa

fy

=

275 MPa

Slab Loads:

Service Live Load:

Service Dead Load:

SLL

=

4.8 KPa

DLL

=

Details:

Clear Short Span:

Clear Long Span:

La

=

3.50 m

Lb

=

4.75 m

Select Case by pressing the BUTTON at the

right

Solution:

Case :

3 1. Effective Height

h

=

Panel Perimeter

=

23.5+24.75

180

180 =

0.092 m

say

0.100 m

2. Ultimate Load

Consider a meter strip:

Wslab

=

23.56 * b *h

=

23.56 * 1.0 * 0.1

=

2.356 KN / m

Wdl

=

SDL * 1.0 m

=

5.3 * 1.0 m

=

5.3 KN / m

Wll

=

SLL * 1.0 m

=

4.8 * 1.0 m

=

4.8 KN / m

Wudl

=

1.4*(Wslab + Wdl)

=

1.4(2.356+5.3)

=

10.718 KN / m

Wull

=

1.7 * Wll

=

1.7 * 4.8

=

8.16 KN / m

Wu

=

Wull + Wudl

=

4.8 + 10.718

=

18.878 KN / m

3. Calculate Moments Using Coefficients

m

=

La / Lb

=

3.5 / 4.75

=

0.74
