14) Movement

This document contains a calculation sheet for horizontal movement related to a project named Sg Muda. It details the calculations for movement due to creep, shrinkage, and temperature, resulting in a total movement of approximately 10 mm for bearing design purposes. The calculations are based on specific formulas and assumptions regarding the conditions of the bridge.

CALCULATION SHEET Drg. Ref.

PROJECT: Sg Muda Cal. By. HR Date Chd.

CALCULATION OF HORIZONTAL MOVEMENT

A) MOVEMENT DUE TO CREEP

∆cr = Ɛcr x L x savg


= 0.000036 x 26000 x 12
= 11.232 mm

B) MOVEMENT DUE TO SHRINKAGE

∆cr = Ɛsh x L
= 0.0002 x 26000
= 5.2 mm

C) MOVEMENT DUE TO TEMPERATURE

∆th = ɸth x L x ∆t
= 1.20E-05 x 26000 x 12
= 3.74 mm

Assume 1/2 the value of movement due to shrinkage had already taken place before the bridge is in service

Total movement due to Shrinkage and Teperature

∆S-T = 1/2 x∆cr x 1/2 x ∆cr + 1/2 x∆t


= 5.616 + 2.6 + 1.9
= 10.088 mm
Say 10 mm for bearing design purpose.
