Axially Loaded Steel Columns Strengthened with CFRP

During the recent decades, Carbon Fiber-Reinforced Polymer (CFRP) composite materials have proven valuable properties and suitability to be used in the construction of new buildings and in upgrading the existing ones. The objective of this paper is to review the previous work in this area and compare it with the current experimental results to show the design equations for CFRP strengthened steel structural elements. Research findings have shown that CFRP sheets and strips are not only effective in restoring the lost capacity of a damaged steel section, but are also quite effective in strengthening of steel sections to resist higher loads, extend their fatigue life and reduce crack propagation

Pushover Analysis for Cold Formed Storage Rack Structures

This study investigated the progressive collapse of cold formed storage rack structures subjected to seismic loading, using pushover analysis. A simple storage rack cold formed steel structure was analyzed with static, non-linear procedure in accordance with FEMA 356 specifications and progressive collapse recorded such as occupancy, immediate occupancy, life safety and collapse prevention. Pushover analysis was found to be a useful analysis tool for the conventional storage racking systems giving good estimates of the overall displacement demands, base shears and plastic hinge formation

MODELING OF ULTIMATE LOAD FOR LIGHTWEIGHT PALM OIL CLINKER REINFORCED CONCRETE BEAMS WITH WEB OPENINGS USING RESPONSE SURFACE METHODOLOGY

ABSTRACT This paper proposes a model for ultimate load of lightweight Palm Oil Clinker (POC) reinforced concrete (RC) beams with web openings using the Response Surface Methodology (RSM). The suggested model is developed to predict the ultimate load for a comparison with the experimental measurements and optimizes load capacity and design accordingly. The ultimate load has been investigated against three parameters, namely depth of beams, location of openings and length of openings. The results of this work show that the developed model has good adaptability and high accuracy
