Reference Calculation OutputFrame Analysis

To check the effect from vertical and lateral loads, frame analysis was

done using the computer package "ETAB". When considering the whole

building, frames in "Y" direction are the critical frames. Hence a full frame

analysis done for frame 7(A-K) is detailed here.

To consider alternate span loading and lateral load effects in "Y"

direction, eight static load cases were selected. Another two static

load cases were selected to represent the loading in "X" direction.

To reprent alternate span loading in "Y" direction, two static load

cases for Dead loads as Dead 1 (D1) and Dead2 (D2); and two static

load cases for Live loads as Live 1 (L1) and Live 2 (L2); were selected.

Wind 1(W1) static case was taken for Wind flows from front side of

building and Wind 2 static case was taken for the wind flows from rear

side of building. Static load cases " N1" and "N2" was taken to consider

notinal horizontal loads to the building. When notional load is critical than

BS 8110 factored wind force, unfactored notional loads were taken instead to

Cl. 3.1.4.2 Wind force, as per Cl. 3.1.4.2 of BS 8110

To get the axial force which exerted from the "X" direction of the frame,

two static cases called, Dead 3 (D3) and Live 3 (L3) were taken to

consideration.

Static Load Cases:

Dead

Dead 1 (D1) To represent the alternate span loading

Dead 2 (D2) in "Y" direction.

Dead3 (D3) - To represent the loading exerted from

"X " direction.

Live

Live 1 (L1) To represent the alternate span loading

Live2 (L2) in "Y" direction.

Live 3 (L3) - To represent the loading exerted from

"X " direction.

Wind 1 (W1) To represent the wind loading in front

Wind 2 (W2) and rear in "Y" direction.

Notinal Loads (N1) To represent the notinal loading

Notinal Loads (N2) in front and rear in "Y" direction.

From above static load cases, following seven load combinations were taken to consideration.

Calculation of Dead loads and Imposed loads:

Design loads for supporting beams were calculated by using shear co-efficients of two way spaning slabs.

Specimen calculation for frame on grid 7 (A-K) at First floor level:

For Span K-J:

Dead Load

Load from slab = 10.9kN/m(0.4x4x3.6)+(0.36x4x3.6)

Load from beam = 2.7 kN/m(0.3x0.375x24)

No wall load is present at this span

Load from finishes = 3.0 kN/m(0.4x4x1)+(0.36x4x1)Total dead load = 16.6 kN/m

Imposed load

Imposed load for general office area = 3.5 kN/m2

Imposed load for span K-J = 10.6kN/m(0.4x4x3.5)+ (0.36x4x3.5)

Simillary for other spans and other floors dead loads and imposed loadswere calculated. Specimen calculations for beam 7(K-A) of Ground floor

Wind loads were also calculated for frame on grid 7(A-K) according to the CP-3 Chapter V to evaluate horizontal loads.
