Abstract

This study presents a simulation analysis of the non-linear behavior of retrofit concrete material due to uniaxial loads modeled in the form of cylinders measuring 150 mm in diameter and 200 mm in depth using the ABAQUS. Analysis of this auxiliary program includes cases of normal concrete retrofit, concrete with retrofit concrete with a composition of 1% steel fiber, and concrete with retrofit concrete composed of 2% steel fiber. From the results of the study conducted, it was shown that in modeling the properties of concrete damaged plasticity in ABAQUS, the use of accurate compressive behavior equations for concrete cases with normal concrete retrofit was core concrete and retrofit concrete using the Alfarah, et al equation. For the case of concrete with steel fiber composition retrofit, core concrete uses the Alfarah equation, and retrofit concrete uses Zhou Jiajia, et al. Whereas to model the tensile behavior accurately in the case of concrete with normal concrete retrofit using the Alfarah, et al equation. And the case of concrete with retrofit steel fiber compositions using the CEB-FIB equation and the Ali & Nehdi equation. The results of ABAQUS analysis of force vs. displacement show a graphical pattern close to the similarity of retrofit concrete column experimental results ECC1 error force ratio and displacement 14.86% and -10.60%, and ECC2 14.82% and 8.01). Based on the stress analysis shows that there is a gradual increase in core concrete where the peak of stress is found in the core area of the concrete core and in the retrofit area is divided into two regions, namely stressing on the center and pulling on a small part of upper and lower column retrofit.

Abstract

Commonly joints problems (especially high strength bolt) were stiffness, ductility, and construction costs. This research was conducted with purpose to analyzed inner force and behavior that could be occurred on high strength bolted joints in steel frame using IWF profiles, such as stress, and reaction force-displacement. This study was divided into 2 step, first step was modeling on finite element software, and second step was analyzing the results and comparing it with the results from experimental study as validation base. In bolted joints model showed the best value on third trial with displacement value of 98,97 mm and reaction force of 41,57 KN. With validation to experimental results each one were 93,45% and 94,05%. Accuracy of hysteretic loop curve area was 98,46%.
