چکیده
The main challenge in designing Light-Weight Concrete (LWC) is to adapt most of the design, production, and execution rules from normal-weight concrete. Carbon Fiber-Reinforced Polymer (CFRP) composites provide strength stiffness composite system. This study investigated an LWC flat slab with CFRP when subjected human-induced vibration. was determined by finding natural frequency comparing it acceleration limit ratio (human perception vibration) 0.5% g. In cases, vibration characteristics are examined using commercial software based on Finite Element Analysis (FEA) methods that powerful tools, but user needs understand underlying assumptions implemented, especially for reinforced concrete floor systems where inherent attributes, such as cracking, play important role determination characteristics. used Abaqus CAE. idea this cannot detect behavior cracks structures over years effect frequencies, depends modulus elasticity not moment inertia. Therefore, equation has a component constantly accounts level cracking slabs. theoretically detailed calculations provided Design Guide Vibrations Reinforced Floor Systems. Then, constant k1 multiplied E substituted latter's place ensure right without CFRP. also properties how represent Abaqus. numerical results showed good agreement FEA acceptance criteria walking excitations increased

Nonlinear finite element analyses of FRP-strengthened reinforced concrete slabs using a new layered composite plate element
A new layered 4-node, 24-degrees of freedom rectangular composite plate element is developed in this paper for nonlinear finite element analyses of FRP-strengthened RC slabs. The layered approach is used to form an integrated plate element for modelling of concrete, FRP, adhesive layer and steel reinforcement with a perfect bond assumption between each layer.

متن کاملBehaviour of FRP strengthened concrete columns under eccentric compression loading
This paper presents results of testing eccentrically loaded columns externally wrapped with two types of materials. Six cylindrical (205 mm diameter and 925 mm height) plain columns were cast and tested. Half of the columns were wrapped with GFRP and the other half with CFRP. All columns were tested by applying an axial load at 50 mm eccentricity. In each group (GFRP or CFRP wrapped) of columns...
