Performance and Analysis of Frames With URM Infills
The interaction of unreinforced hollow concrete block masonry (URM) infill walls and gravity load designed (GLD) frames has been studied at Cornell University. The primary goal of this...

Behaviour of Concrete Masonry Infill - Steel Frame Structures
Twenty-eight masonry shear panels infilled in steel frames were tested to ultimate strength under in-plane, horizontal loading applied at roof level. The parameters investigated in this...

Lateral Response of Unreinforced Masonry Infill Frame Panels
This paper presents the results of the out-of-plane testing phase of the National Science Foundation Grant BCS 9102347. This project addresses the out-of-plane response to lateral loading...

Experimental Evaluation and Finite Element Analysis of Masonry-Infilled R/C Frames
Eleven tests were conducted on 1/2-scale, single-story infilled frame specimens to study the influence of the relative strengths of the infill panels and the bounding frames and the frame...

Damage Tolerance Analysis in Structural Rehabilitation
The rehabilitation of existing structures requires an evaluation by the structural engineer of past performance to determine the extent of existing damage. Following evaluation of the...

How to Optimize Light-Gage, Cold-Formed Steel Beams
The Illustrative Examples section of the AISI Cold-Formed Steel Design Manual (AISI 1989) demonstrates how to analyze a number of different cold-formed steel sections. This paper applies...

Optimization for Earthquake Loads
Structural optimization for seismic loads can be approached from a deterministic or nondeterministic point of view. Deterministically, the major difference between optimization of statically...

Structural Analysis for Structural Design
This paper presents a simple extension to conventional structural analysis that serves to provide additional information that is of significant use to the structural design process. Specifically,...
