Upward Uniform Load using Load Balancing Method Solution

STEP 0: Pre-Calculation Summary

Formula Used

Uniform Load = 8*Prestressing Force*Sag Length of Cable/Span Length^2
w_b = 8*F*L_s/L^2
This formula uses 4 Variables

Variables Used

Uniform Load - (Measured in Newton per Meter) - Uniform Load is a load that is distributed or spread across the whole region of an element such as a beam or slab.
Prestressing Force - (Measured in Kilonewton) - Prestressing Force is the force internally applied to the prestressed concrete section.
Sag Length of Cable - (Measured in Meter) - Sag Length of Cable is the length measured at Midway between Supports is vertical sag at midpoint of cable.
Span Length - (Measured in Meter) - Span Length is the end to end distance between any beam or slab.

STEP 1: Convert Input(s) to Base Unit

Prestressing Force: 400 Kilonewton --> 400 Kilonewton No Conversion Required
Sag Length of Cable: 5.2 Meter --> 5.2 Meter No Conversion Required
Span Length: 5 Meter --> 5 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

w_b = 8*F*L_s/L^2 --> 8*400*5.2/5^2

Evaluating ... ...

w_b = 665.6

What is Load Balancing method?

Load balancing is a design method for prestressed structural members, primarily beams and slabs, that provides efficient use of materials. When using load balancing, the prestressing tendon is designed for a prestressing force and eccentricity in order to ‘balance’ all or a portion of the dead load. Commonly the procedure is used for post-tensioned cast in place structures. However, it is not used typically for precast, pre-tensioned members.

How to Calculate Upward Uniform Load using Load Balancing Method?

Upward Uniform Load using Load Balancing Method calculator uses Uniform Load = 8*Prestressing Force*Sag Length of Cable/Span Length^2 to calculate the Uniform Load, The Upward Uniform Load using Load Balancing Method is defined as the imaginary load which is distributed equally in the upward direction for analyzing prestressed concrete structures. Uniform Load is denoted by w_b symbol.

How to calculate Upward Uniform Load using Load Balancing Method using this online calculator? To use this online calculator for Upward Uniform Load using Load Balancing Method, enter Prestressing Force (F), Sag Length of Cable (L_s) & Span Length (L) and hit the calculate button.
