Strut-and-tie model (STM), with its truss analogy, is yet a powerful tool for analyzing and
designing complex prestressed and reinforced concrete structures. Which represents a …

Conventional trial-and-error methods are not efficient in developing appropriate strut-and-tie
models in complex structural concrete members. This paper describes a performance-based …

Performance-Based Optimization of Structures introduces a method to bridge the gap
between structural optimization theory and its practical application to structural engineering …

This paper deals with automatic generation of optimal strut-and-tie models in prestressed
concrete beams by the performance-based optimization (PBO) method. In the present …

In this study, a literature review was conducted to establish the background of current
specifications and to evaluate the applicability of various theories and methods for design of …

Anchorage zones of posttensioned structures are prone to splitting cracks, necessitating
rational reinforcement design methods for anticracking in such regions. This paper presents …

The post-tensioned anchorage zones are generally subdivided into local and general
zones, which are treated with semi-empirical approaches and strut-and-tie models …

In prestressed concrete structures, improper design and detailing of the anchorage zone
frequently cause bursting cracking along the tendon path. Due to the complex stress state in …

The strut-and-tie model (STM) has been adopted as a preferred methodology for the design
of the post tensioned concentric anchorage zones. However, the STM is just a design model …

This article presents a method for the automatic generation of optimal strut-and-tie models in
reinforced concrete structures using a bi-directional evolutionary structural optimization …
