This paper aims to determine a computer-aided mold design algorithm for precast concrete products to be produced by external
vibrators. For this purpose, the behaviors of two different precast
concrete molds were investigated experimentally and analytically.
Experiments were performed under vibration with the use of a
computer-based data acquisition system. Transducers were used to
measure time-dependent lateral displacements at some points on
the mold while it is empty and full of fresh concrete. Test results
indicate that the difference between displacement amplitudes of
empty and full molds is considerably high.
Three-dimensional analytical modeling of molds used in
experiments was prepared by finite element method using software. Modeling of the full mold was made to solve the problem
of dynamic interaction of fresh concrete mold. In light of experimental, numerical, and literature studies, a mold design algorithm
was established for precast concrete elements. Using this algorithm, a computer-aided mold design was carried out theoretically
for a sample mold system
