Abstract

In this paper, an experimental of size effect on shear stress of concrete beam without
coarse aggregate is described, where concrete beams without using transverse reinforcement and
using longitudinal reinforcement with a maximum ratio. The study explains the size effect of
shear stress that can be bears by concrete beams with shear arm ratio a/d 2.744. The test object
in this research is cylinder with diameter 100 mm and height 200 mm and beam with variations
of height 60 mm, 90 mm, 120 mm, 150 mm, and 180 mm with width 60 mm and length 1100
mm. From the test results of the compressive strength test, compressive strength of concrete
between 58.51 MPa to 99.8 MPa. Based on shear strength test, diagonal tension failure and shear
tension failure occurred on the beam. The test results show that the shear stress is size dependent.
The shear stress will decrease with rising height of the beam. The pattern of changes in shear
stress value due to changes in beam height resembles the results of previous studies by Kani
(1967).
