- Nonlinear Analysis of Steel-Concrete Composite Structures: State of the Art
- This paper presents the state of the art of nonlinear analysis of steel-concrete composite structures. The focus is on frame elements, which are computationally faster than continuum finite element models. Section models are presented, with a review of resultant and fiber models and a discussion of possible practical applications. The...

- Size Effect on Fatigue in Bending of Concrete
- This paper presents a semi analytical method to predict fatigue behavior in flexure of concrete in the case of maximum flexural moment larger than that of the first crack moment based on force equilibrium in the critical cracked section. Eight series of beams, with heights from 50 to 800 mm,...

- Influence of Supporting Base Characteristics on Shrinkage-Induced Stresses in Concrete Pavements
- This paper presents an analytical model for prediction of shrinkage-induced stresses and displacements in concrete pavements due to the restraint of the supporting base. The model relies upon the interfacial friction stress transmitted between the slab and base as the fundamental mechanism of restraint provided by the base when concrete...

- Measuring and Modifying Interface Properties of PVA Fibers in ECC Matrix
- A single fiber pullout test was used in this study to measure the bond properties of polyvinyl alcohol fibers that are available at various diameters in a mortar matrix. Despite short fiber embedment lengths, the small diameter fibers ruptured during the pullout tests. However, it is shown that even if...

- Influences of Fibers on Drying Shrinkage of Fiber-Reinforced Cementitious Composite
- An analytical model has been formulated for the drying shrinkage performance of a fiber-reinforced cementitious composite. The model is based on the assumption that shear stress is produced between the fiber and surrounding matrix as the matrix shrinks. This shear stress in turn influences the matrix deformation behavior resulting in...

- SIM-UTILITY: Model for Project Ceiling Price Determination
- Before considering bids submitted by competing contractors for a public procurement project, the owner should determine a project ceiling price or cost estimate to use as a reference point for evaluating the bids. A high ceiling price conflicts with the owner's interests in minimizing costs. This paper proposes a model...

- Influence of Project Type and Procurement Method on Rework Costs in Building Construction Projects
- While it is widely recognized that additional costs due to rework can have an adverse effect on project performance, limited empirical research has been done to investigate the influencing factors. The research presented in this paper aims to determine the influence of different project types and procurement methods on rework...

- Sliding Mode Control of Cable-Stayed Bridge Subjected to Seismic Excitation
- The working group on bridge control within the ASCE Committee on Structural Control recently initiated a first-generation benchmark problem addressing the control of a cable-stayed bridge subjected to seismic excitation. Previous research examined the applicability of a LQG-based semi-active control system using magneto-rheological MR dampers to reduce the structural response...

- Reliability-Based Structural Safety Assessment Using Risk-Ranking Decision Analysis
- Information about present and anticipated bridge reliabilities can be used in conjunction with decision models to provide a rational decision-making tool for the assessment of bridges and other structural systems. The present paper presents a broad overview of reliability-based assessment methods and will then focus on decision-making applications using updated...

- Feasibility and Optimization of Rigidified Inflatable Structures for Housing
- Rigidified inflatable structures RIS, previously used and tested in space technology applications, are of potential interest to residential construction. This paper examines RIS technology is examined and considers the case of a single, exterior wall subjected to wind and roof load. A design approach for RIS technology in residential construction...

- Influence of Reinforcing Bars on Shrinkage Stresses in Concrete Slabs
- It is well known that cracking in concrete slabs significantly influences their service life. Concrete shrinkage may be the principle reason for the initial crack formation in the slabs. This paper presents an attempt to provide an analytical tool for the prediction of stress distribution in reinforced concrete slabs after...
