Overestimation of load-resisting capacity in double-span welded steel beams: a comparative FEM study incorporating ductile damage and element deletion

Jurnal Ilmiah SINERGI
The study investigates how different finite element modelling assumptions affect the predicted load-resisting behavior of welded beam-column connections in double-span steel beam systems subjected to column-removal scenarios.

Performance of the PR connections under combined Axial-tension and moment loading

Electronic Journal of Structural Engineering, 2010
The inherent moment capacity of bolted top-seat angle connections with double web angles (TSDW), categorized as partially restrained (PR) connections according to AISC-LRFD specifications, can be considered in analyses of semi-rigid connections ...

Relative dimension of morphisms and dimension for algebraic stacks

, 2013
Motivated by applications in moduli theory, we introduce a flexible and powerful language for expressing lower bounds on relative dimension of morphisms of schemes, and more generally of algebraic stacks.

Designing by Geometry. Rankine's Theorems of Transformation of Structures. [PDF]

, 2010
William John Macquorn Rankine (1820-1872) was one of the main figures in establishing engineering science in the second half of the 19th. Century. His Manual of Applied Mechanics (1858) gathers most of his contributions to strength of materials and ...

Strengthening of Precast RC Frame to Mitigate Progressive Collapse by Externally Bonded CFRP Sheets Anchored with HFRP Anchors

Advances in Civil Engineering, 2018
Currently, the robustness of precast reinforced concrete frames is attracting wide attention. However, avoiding “strong beams and weak columns” during strengthening against progressive collapse is a key problem.

Impact of accurate reinforcement steel assessment on structure longevity and progressive collapse resistance

Sustainable Structures
Current standards for reinforcement steel may not accurately reflect the actual properties of steel used in construction, leading to potentially underestimating the resistance and longevity of structures.

Prediction model for progressive collapse resistance of concrete beam-column subassemblies considering tensile catenary action using machine learning algorithms

Results in Engineering
Following the gradual crushing and spalling of concrete at large deformations, tensile catenary action (TCA) usually develops in axially restrained reinforced concrete beam-column subassemblies and provides a crucial resistance mechanism to avoid ...

Experimental study on catenary action of RC beam-column subassemblages

, 2010
Catenary action is considered as the last defense of a structure to mitigate progressive collapse, provided that the remaining structure after an initial damage can develop alternate load paths and a large deformation has occurred in the affected beams and slabs. As a result, catenary action requires high continuity and ductility of joints.

On the existence of maximal orders

, 2011
We generalize the existence of maximal orders in a semi-simple algebra for general ground rings. We also improve several statements in Chapter 5 and 6 of Reiner's book concerning separable algebras by removing the separability condition, provided the ...
