Achievements of Truss Models for Reinforced Concrete Structures
Reinforced Concrete Structure Truss Model Constitutive Law Material and Geometric Nonlinearities Concrete Cracking Reinforcement Yield Concrete Ultimate Compressive Strength Plastic Hinge RC Column Confinement Buckling of Inner Concrete Struts Global Instability
2013/1/31
Achievements are presented for truss models of RC structures developed in previous years: 1. Two constitutive models, biaxial and triaxial, are based on regular trusses, with bars obeying nonlinear un...
A practical design method for reinforced concrete structures with viscous dampers
Viscous damper Design method Reinforced concrete structure Wenchuan Earthquake
2014/4/10
As a result of the 2008 Wenchuan Earthquake, the Chinese government issued a modified seismic code with increased protection categories and seismic intensities. According to the new code, a lot ...
Flexural performance of fire damaged and rehabilitated two span reinforced concrete slabs and beams
fire damage concrete continuous members rehabilitation flexural rigidity bearing capacity
2014/4/10
Five two-span reinforced concrete (RC) slabs and seven two-span RC beams were tested under the ISO 834 standard fire with different durations. CFRP strengthening was then applied to some of the specim...

Gravity Load Redistribution Progressive Collapse Resistance 20-Story Reinforced Concrete Structure following Loss Interior Column
2014/4/10
Progressive collapse, which is defined as the spread of an initial local failure from element to element, eventually resulting in the collapse of an entire structure or a disproportionately large part...
Size Effect in Reinforced Concrete Beams With Short Shear Span and Without Stirrups
Reinforced concrete Bazant's size effect theory Carpinteri's size e ect theory
2009/10/14
For the to design of reinforced concrete beams with no stirrups, di erent equations have been formulated
by researchers. These equations either are on the side of extreme safety or do not include the...
An Experimental Study on the Effect of Steel Fiber Reinforced Concrete on the Behavior of the Exterior Beam-Column Joints Subjected to Reversal Cyclic Loading
Beam-column joint Steel fiber reinforced concrete Ductile behavior
2009/10/12
For the ductile behavior of beam-column joints, closely spaced transverse reinforcement is required by earthquake codes. However, placement of this reinforcement in joints always causes some dicultie...
Nominal moment capacity of box reinforced concrete beams exposed to fire
Fire reinforced concrete nominal moment capacity beam box section cover concrete
2009/9/30
The performance of steel reinforced concrete (RC) beams with a box cross section exposed to fire is studied. The cross-section is divided into an appropriate number of segments so that non-uniform tem...
