Nonlinear Behavior of Northlight Reinforced Concrete Shells
The behavior of northlight shells is very sensitive to the boundary conditions at the top and bottom edges of the shell. The aim of this paper is to investigate the structural action of...
Study on Reinforced Concrete Cylindrical Shells with Edge Members under Impact Loading
The strength, cracking patterns and the other nonlinear dynamic behaviors of reinforced concrete roof-type circular cylindrical shells influenced by edge member stiffness and supporting...
Nonlinear Analysis of a Reinforced Concrete Folded Plate Structure
This paper deals with the ultimate load analysis of a reinforced concrete (RC) folded plate shell subjected to dead load and monotonically increasing live loads, statically applied, using...
Spatial Structures Erected out of Thin Shell Elements Fabricated on Plane Followed by Bending
The paper offers the examples of spatial structures of average spans (up to 24 m) and engineering structures made of prefabricated curvilinear elements originally having a plane form....
Ultimate Strength of R/C Cooling Tower Shell
Reinforced concrete(R/C) cooling towers are the largest, thin shell structures. It is important to assess the ultimate strength of R/C cooling tower shells subjected to wind load. In the...
Repair of a Cracked Cooling Tower Shell Based on Numerical Simulations
The present condition of a 30 years old cooling tower shell made of reinforced concrete is characterized by a relatively large number of long, thermally induced meridional cracks. For...
Design for Durability for Large Reinforced Concrete Shells
Classical design concepts restrict themselves to sufficient structural safety, using linear analysis methods. Durability questions are mainly treated independently. Modern computer simulations...
Punching Shear of Reinforced Concrete Shell Structures
In reinforced concrete shells punching shear failure may take place, if heavy concentrated loads are applied. Such failure is undesirable, since it does not provide adequate warning and...
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...
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...
Distributed Flexibility Models for Nonlinear Analysis of RC Structures
The application of distributed flexibility member models in inelastic analysis of reinforced concrete (RC) structural systems is examined. While the utilization of flexibility-based formulations...
RC Beam-Column Element for Nonlinear Frame Analysis
Recent studies have shown that beam-column finite elements that enforce equilibrium rather than compatibility along the element are better suited for the description of the strength and...
Finite Element Analysis of Shear in RC Girders
Two complementary approaches are presented to model the shear behaviour of reinforced concrete structures. A local one, based on a probabilistic modelling of cracking, accounts for local...
Fast Monte Carlo Simulations and Safety Index Checking
This paper presents recent techniques which require a small number of simulations to assess the structural reliability. They combine both the concept of importance zones in the random...
Rehabbing Bridges Under Traffic
Four urban examples demonstrate how an owner's decision to keep it open during rehabilitation construction forces the designers to contend with an extra set of problems. Reanchoring...
An Object-Oriented Approach for Reinforced Concrete Design
The use of the object-oriented programming approach in developing applications for the analysis and design of reinforced concrete members is discussed. Two object oriented programming...
Evaluation of Software for Analysis and Design of Reinforced Concrete Structures
A study to verify the accuracy of two structural analysis and concrete design programs and to evaluate their functionality was conducted. The evaluation was based on a comparison of results...
Discrete Modeling of Soil-Structure Interaction Under Dynamic Loading
A proposal of discrete modeling useful to describe behavior of structures burried in the ground under air explosion is presented. In the modeling emphasis is laid on determining the space...
