Nonlinear elastic-plastic analysis of reinforced concrete column-steel beam connection by RBF-FD method

نویسندگان

چکیده

In this paper, the elastic-plastic analysis of cantilever beam and Reinforced Concrete (RC) column-Steel (S) connection are studied using Radial Basis Function- Finite Difference (RBF-FD) method. A direct method bilinear nodes is proposed to deal with instability caused by first derivative calculation in traditional RBF-FD Based on idea gradient projection method, improved further applied multi-domain material nonlinearity. Numerical results validated finite element software (COMSOL).

Nonlinear Analysis of Reinforced Concrete Frames by a Combined Method

A more realistic and hence nonlinear analysis of reinforced concrete structures is becoming increasingly important. A combination of the displacement method, the transfer matrix method, and a crosssection module is suggested which leads to an effective analysis method for reinforced and prestressed concrete frames. The combined method considers both material and geometrical nonlinearities inclu...

Finite element analysis of a rigid beam to column connection reinforced with channels

Abstract: This research work presents a new rigid connection constructed with channels. In order to assess its hysteresis behavior, three specimens with different cover plates and six specimens with different panel zone thickness have been considered. The energy absorbed by the connection and the behavior of the panel zone were studied during cyclic loading and compared with those of connectio...
