Applied Sciences, 2021 Stress is one of the most important physical indexes reflecting the mechanical behavior of concrete structures. In general, stress in structures cannot be directly monitored and can only be estimated through an established model of stress and strain. The

Modelling of Glulam beams pre-stressed by compressed wood
Composite Structures, 2017 Finite element models were, in the first time, developed to simulate the pre-stressing behaviour of Glulam beams with insertion of compressed wood blocks, which were further used to simulate the structural behaviour of the pre-stressed beams subjected to subsequent destructive bending.

Soft Pre-stressed PET Profiles as reinforcing fibers in structural elements made of concrete
Dyna, 2018 The inclusion of pre-stressed PET profiles as reinforcing fibers in structural elements is proposed. The PET-profiles are placed in a unidirectional and bidirectional fiber matrix with soft pre-tensioned condition that they could have advantages in ...

The damage analysis of the reinforced concrete beam and the prestressed reinforced concrete beam
MATEC Web of Conferences, 2018 The paper deals with the finite-element analysis of damage in reinforced concrete beam and prestressed reinforced concrete beam. The steel reinforcement is modeled using non-linear rebar elements and an elastoplastic model of the reinforcement is ...
