Finite Element Analysis of Heavy Duty Riveted Steel Grating Bridge Deck

Abstract

Heavy duty riveted gratings are a good alternative for applications that often employ other deck systems, if they are carefully analyzed under static and fatigue loads. Understanding the static behavior of a riveted steel deck under tire patch loads will aid in establishing a design model based on an effective beam width. In addition, use of a riveted system avoids welded details that may lead to fatigue cracking, thereby improving design life. In this study, analysis of a typical riveted steel deck under a standard AASHTO fatigue truck with a 15% impact factor was conducted. Hand calculations were compared with the results of a finite element model using SAP2000 v19.2.1. Bending moments and stresses were evaluated and compared. Stresses at the rivet hole for the most highly loaded bearing bar were evaluated. A model for fatigue cracking around a rivet hole is discussed.

Numerical and Code-Based Investigation on the Impact of Corrosion on the Ultimate Compressive Strength of Steel Angle Members Using Thickness Reduction Method

“…Many researchers have conducted various studies on corrosion over the past years including publications by Safiuddin [5], Wang et al [6] and El Aghoury [7] who have elaborated on the different types and various factors influencing corrosion. Moreover, there have been several attempts such as the studies by Shaheen et al [8] and Abdulla and Menzemar [9] to numerically investigate the properties of steel members using finite element applications.…”
