Response of high strength concrete columns under fire-induced biaxial bending
… columns, under fire conditions, can experience biaxial bending which can arise due to eccentricity in loading, uneven spalling, or due to significant thermal gradients generated through 1-, 2-, or 3-sides of fire exposure. High strength concrete (HSC) columns are especially prone to such biaxial …

Estudo de flexão composta oblíqua em seções retangulares simétricas
… uniformly distributed reinforcement under biaxial bending. Theoretical bases followed CEB-FIP-1970 recommendations. Comments on grafical methods for design and checking were also presented. Studies on aproximate methods presented by several authors and codes were analysed as to their …

A Hysteresis Model for Reinforced Concrete Space Frame Structures
… of reinforced concrete columns subjected to biaxial bending and varying axial load is proposed. The model, identified as the U-model, is based on cross-sectional properties. The U-model combines the Otani's modification of the Clough model and the Ziegler hardening rule of plasticity theory. …

Background for finite element analysis and experimental testing of glued-laminated space beams
… Pine glued-laminated beams are subjected to bending, bending and compression, and biaxial bending. The beams are tested at service loads and only one beam is loaded to failure. The analysis is performed by using the finite element program ABAQUS. The 3-D beam finite element model used is …

Crash behavior of three dimensional thin-walled structures under combined loading
… energy absorption are proposed. The mechanics of biaxial bending collapse and the collapse under combined bending and compression of thin-walled prismatic member are formulated and initial and subsequent shrinking interaction curves between the loading components are constructed. All the …

Response of Wide Flange Steel Columns Subjected to Constant Axial Load and Lateral Blast Load
… were considered. Major axis, minor axis, and biaxial bending were investigated. The effects of strain rate and residual stresses were examined. The results for each column configuration are presented as a set of curves showing the critical blast impulse versus axial load. The critical blast …

Behavior of structural concrete members strengthened by composite fabrics
… with CFRP fabrics under combined axial load and biaxial bending were also investigated in this research. Seven slender columns with different wrapping methods were tested and analyzed. It can be concluded that both longitudinal and transverse fabric do help increase the load capacity of the …

Bridge approach slab analysis and design incorporating elastic soil support
… partial elastic soil support. Additionally, a biaxial finite-difference model is developed using MATLAB for better understanding the performance of BAS in both longitudinal and transverse directions. Results from uniaxial and biaxial solutions are compared and discussed. Initial construction …

Normal-strength and high-strength concrete columns under cyclic axial load and biaxial moment
The technique of using Carbon Fiber Reinforced Polymer (CFRP) materials to repair and strengthen various concrete members has become popular in the structural retrofitting field as an effective way to enhance the strength and ductility of concrete members due to its superior mechanical properties. …

Bestimmung der bruch- und schädigungsmechanischen Eigenschaften keramischer Filterwerkstoffe aus Kleinstproben
… des Ball-On-Three-Balls-Tests (B3B) wurde die biaxiale Festigkeit in Abhängigkeit der Prüftemperatur bestimmt. Für die kohlenstoffgebundenen Proben wurde weiterhin der Einfluss der Verkokungstemperatur als auch des Kohlenstoffgehalts auf die Festigkeit untersucht. Es konnte ein …

Cyclic behaviour and numerical modelling of cold-formed hollow structural sections [Comportamento ciclico e modellazione numerica di sezioni cave strutturali formate a freddo]
I profili cavi strutturali formati a freddo (cold-formed Hollow Structural Sections, HSS) sono ampiamente utilizzati come colonne nei telai in acciaio resistenti a momento grazie all’elevato rapporto resistenza/peso, alla rigidezza laterale simile lungo direzioni ortogonali e all’elevata rigidezza …
