Structures Concrete

This book discusses the behaviour of isolated concrete bottle-shaped struts affected by internal expansion reactions (ISR). For that purpose, the numerical modelling of damaged concrete was performed using the Concrete Damaged Plasticity Model (CDPM) implemented in ABAQUS and validated the model through Sankovich's tests. A procedure to automatically obtain the concrete plasticity and damage parameters, essential for CDPM, was developed in Matlab. The inputs were the characteristic compressive strength of the concrete, the equivalent length of the finite element mesh and the ratio between the plastic and inelastic compressive strains.

The book introduces the comprehensive analysis methodology regarding progressive collapse, and the critical issues may happen in concrete structures. Main topics include: the influential parameters of the development of the main load-resisting mechanisms; the dynamic effects with sudden column removal scenarios; the contribution of non-structural components to improve the resilience of concrete structures; uncertainties in progressive collapse analysis. Based on the empirical research of the author and his team, the book provides valuable knowledge in the field of progressive collapse and bridges the gap between academic research and practice.
