Analysis and design of disturbed regions with strut-tie models
, 1992 An interactive computer graphics program implementing the Strut-Tie model approach for analysis and design of reinforced and prestressed concrete members is presented. The program consists of three parts.

Optimized Design of Anchor Plates for 2200 MPa-Class Prestressing Anchorage Zones
BuildingsThe strength of prestressed steel strands has developed towards high strength, increasing from 1860 MPa to over 2200 MPa. The stress in the prestressed anchorage zone is more concentrated and complex, and the anchor plates for dispersed loads need to be ...

Insect Science, EarlyView.Using an integrative taxonomic framework that combines COI DNA barcodes, geometric morphometrics and phylogeography, we revise the assassin bug genus Tapirocoris and recover seven well‐supported species, including four newly described cryptic species.

Design of Simply Supported Deep Beams Using Strut-and-Tie Models [PDF]
, 2003 A procedure to calculate the amount of reinforcement and the strength of deep beams based on strut-and-tie models is presented. The proposed design equations were calibrated using experimental results from 175 simply supported beams found in the ...

The Howard Journal of Crime and Justice, EarlyView.ABSTRACT The cultures and governance of security markets in the United Kingdom are often characterised through a paradoxical narrative of simultaneous state retreat and progressive advance. In the face of repeated recent high‐profile security failures, and global changes in material political economy, we argue that UK security governance is adapting to

, 2018 The shear resisting actions in reinforced concrete elements without transverse reinforcement is analyzed by means of optimized strut-and-tie models with concrete ties. Biaxial failure criteria are used for uncracked and cracked regions.

Development of strut and tie models for simply supported deep beams using topology optimization [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2008 Generally, structural members can be broadly divided into two regions, namely B, or Bernoulli regions, where the strain distributions are linear and D, or Disturbed regions, where the strain distributions are nonlinear While well defined theories are ...

METHODS FOR CALCULATING THE CONCRETE CORE OF LOOPED REINFORCEMENT JOINTS WITHOUT REINFORCEMENT [PDF]
Journal of Mechanics of Continua and Mathematical SciencesThe article presents a comparative analysis of four methods for calculating the concrete core of looped reinforcement joints without additional reinforcement, including the NIIES Hydroproject method based on Mohr's strength theory, the strut-and-tie ...

Analysis of nodal stress on reinforced concrete two-pile caps supported on steel piles
Revista IBRACON de Estruturas e Materiais, 2020 : Reinforced concrete pile caps may be designed trough plastic models (strut and tie model) or models based on bending theory. The formulae available for verifying the stress is based on caps supported on concrete piles, with few studies about the stress

Journal of Anatomy, EarlyView.We examined morphology, 3D arrangement, and mineral amount in cartilaginous vertebrae from four lamniform shark families (Alopiidae, Carchariidae, Cetorhinidae, and Lamnidae). We identified family‐specific mineralization trends, and regional patterning of structures along the column.
