Flexural and Shear Moduli of FRP Beams
The analysis and design of structures of pultruded fiber reinforced plastic (FRP), constant cross-section, commercially produced, beams is discussed in the context of a shear deformation...
Analytical Model for RC Panels Under Cyclic Load
There are several existing constitutive laws for cracked concrete and steel in RC developed in Okamura laboratory. These models have been developed and verified through reversed uniaxial...
Panel-Sheathed Shear Walls ? Past and Future
In order for a building to resist the lateral forces caused by wind or earthquake, it is necessary that the building include a lateral force resisting system. When the walls are designed...
Study of Partially Prestressed Beams With Unbonded Post-Tensioning
Test on partially prestressed members with bonded Post-Tensioning started recently. Experimental information regarding partially prestressed members having unbonded post-tensioning is...
Shear Strength of P.P.C. Beams
50 beams of partially prestressed concrete were tested and 82 data of the ultimate shear-strength were obtained. Based on these results, this paper studies the effects of the degree of...
Time Dependent Analysis of Partially Prestressed Composite Members
The object of the paper is to develop a computer based procedure for analysis of members made up of precast prestressed concrete sections with cast-in-place topping. The procedure accounts...
Guidelines for Application of FEM to RC Design
In this paper, the main contents of the guidelines for the application of FEM analysis to the design of reinforced concrete structures are presented. The guidelines were published by the...
Macroscopic Models for R/C Shear Walls
In this paper, the discussion is mainly focused on four macroscopic models, recently proposed by Japanese researchers, for predicting ultimate strength of reinforced concrete (R/C) shear...
Verification of Macroscopic Models or RC Walls by FEM
Several macroscopic models based on the limit analysis have been proposed for obtaining the ultimate strength of reinforced concrete shear walls in Japan. When using these models, it is...
Parametric Analyses of RC Shear Walls by FEM
In this paper, nonlinear behavior of reinforced concrete shear walls is studied by using the finite element analysis. We applied numerical analyses to a wide range of parameters, such...
Stress Analysis of the Liner and Liner Anchorage System Near Penetrations in a Reinforced Concrete Reactor Containment
An overpressurization experiment was conducted on a scale-model of a reinforced concrete containment building. The test was terminated when tears formed in the steel liner. Virtually all...
Inelastic Response of Buried Pipelines Due to Landslide Effects
During earthquakes, a buried pipeline may experience significant loading as a result of large relative displacements of the ground along its length. Large ground movements can be caused...
Remote Automatic Data Acquisition Systems
Personal computers have been used on two projects to monitor peformance of structures in an automatically triggered mode. In both cases a local PC is used to continually monitor a triggering...
Buckling Criteria for Earthquake-Induced Overturning Stresses in Cylindrical Liquid Storage Tanks
Perhaps one of the most common forms of seismic damage to cylindrical liquid storage tanks made out of steel is buckling of the tank wall due to vertical overturning stresses. Buckling...
Biaxial Damage Assessment
The structural system under investigation is a frame subject to seismic excitations. The analysis accounts for the spatial distribution of beams, columns and bracing system. It also considers...
Influence of Geologic Development on Horizontal Stress in Soil
Geologic history commonly controls the stress in natural soils, so that an understanding of the geology allows an assessment of the horizontal stress. This paper describes mechanistically...
Cyclic Behavior of Natural Overconsolidated Clay in Two Loading Modes
One-way, stress-controlled, cyclic triaxial compression tests were conducted on a heavily overconsolidated (Ko > 1), slickensided, natural clay with a view to modeling its cyclic...
First-Order Estimation of Ko in Sands and Clays
The in-situ horizontal stress coefficient (Ko) is known to be the dominant design parameter controlling the side resistance of deep foundations....
Jet Grout Stabilization of Peaty Soils Under a Railway Embankment in Italy
The construction of two railway embankments on a peaty soil deposit up to 7m thick required a foundation improvement program meeting very strict specifications in terms of environmental...
Tangent Modulus of Piles Determined from Strain Data
When evaluating measurements of strain or telltale shortening of a pile subjected to loading test, precise knowledge of the 'elastic' modulus is necessary. By means of plotting and analyzing...
