Seismic Design of Highrise Building with Mega Frame
The NEC corporation head office building is under construction at Shiba Minato-ku, Tokyo, Japan. This building is a highrise building of steel structure with the height of 180m. The structural...
Structural Considerations in Design and Construction Process of a 25 Story Office Building
This paper introduces an example in which a steel office building of 25 stories above the ground was constructed employing innovative techniques. One of them was the use of precast concrete...
Seismic Design of a Long-span Space Structure
This structure consists of a 5 layered complex shape of long-span steel roof structure, and reinforced concrete (RC) and steel reinforced concrete (SRC) supporting structures. The roof...
Implications for Limit State Design of Inverted V Braced Steel Structures
Inverted V braced steel structures with backup ductile moment-resisting frames forming a dual system, exhibit complex inelastic behavior under severe seismic excitations. Thus, current...
Seismic Load Effects on a Scaled Model Structure
A long term observation on a scaled steel braced frame model with intentionally reduced seismic strength is ongoing since 1983. This paper examines the seismic load effects of two earthquakes...
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...
A Damage Model for Reinforced Concrete
The damage index developed by the authors models concrete damage as a low-cycle fatigue phenomenon. By quantifying the energy dissipated as a fraction of the total energy dissipation capacity,...
Seismic Vulnerability Evaluation in Japan
The state of the art in Japan is reviewed on the evaluation of the seismic capacity of existing low- to mid-rise reinforced concrete buildings, taking into account the different resistance...
Comparison of Slitted and Non-Slitted R. C. Shear Walls With Boundary Elements Under Horizontal Forces
This paper compares the differences of aseismic behaviours between slitted and non-slitted shear walls under horizontal forces. There are 5 specimens for slitted shear walls and another...
Nonlinear Analysis for the Aseismic Strength of Highrise Steel Frame With Semi-Rigid Joints by Pseudo-Elastic Approach
This paper suggests that the direct stiffness method is still useful in dealing with the nonlinear analysis for the aseismic capacity of highrise steel frame while the Pseudo-elastic approach...
Effects of Semi-Rigid Connections and P-? Forces on the Optimum Design of Seismic Steel Frames
By utilizing methods of optimality critera and constraint gradients, the minimum weight design of semi-rigid planar steel frames subjected to static and seismic excitations is presented...
Amelioration of Stirrup and Compression Reinforcement on the Ductility of Reinforced High-Strength Concrete Beam
18 rectangular high strength concrete beams were tested to investigate their ductile behavior. The results show that it will be more advantageous, for ductility, to choose the compressive...
Study of the Seismic Behavior of Retrofitted Reinforced Concrete Buildings
Over ten years experimental research in Japan on the seismic behavior of retrofitted reinforced concrete buildings is reviewed. Emphasis is put on the improved strength and/or ductility...
Recent Research on Repair and Strengthening of Reinforced Concrete Structures
As part of the research effort organized following the 1985 Mexico City earthquake, a series of tests were conducted at the University of Texas at Austin to assess the performance of redesigned...
The 1988 UBC Seismic Provisions for Steel Structures?An Overview
This paper will give the reader an introduction to the seismic design provisions for steel structures in the 1988 Uniform Building Code. Chapter 27 in the 1988 UBC now contains over ten...
1988 SEAOC and UBC Seismic Provisions
This paper highlights the major improvements to seismic design provisions incorporated in the 1988 Structural Engineers Association of California (SEAOC) 'Blue Book'...
Response of Concrete Buildings to Lateral Forces
ACI-ASCE Committee 442 (Response of Concrete Buildings to Lateral Forces) has just issued its report (ACI-ASCE 442 1988a). In that Report, the performance of reinforced concrete buildings...
