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...
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...
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'...
Assessment of Transmission Line Foundations
Electric utilities are faced with the need to build new transmission lines or to upgrade existing lines to meet future demands. Because of economic constraints and the difficulty of obtaining...
Making Amends with Nature
The U.S. salmon population has been decimated in the last half-century, principally because of hydropower. In the nation's focus on alternate and clean energy sources, fish...
An Evaluation of Pile Design in Fraser River Delta Using In-Situ Tests
Modern methods of pile design often take advantage of in-situ test data. Thirteen axial pile capacity design methods have been evaluated using the results from eight full-scale pile load...
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...
Design and Construction of Stone Column Reinforced Cofferdams
A recent expansion of the North Carolina State Port Facility, at Wilmington, involved the use of six cellular cofferdams as earth retaining structures during dredging and final filling...
Power Pole Foundations in Reclaimed Mining Area
In central Florida, where strip mining for phosphate ore is a primary industry, street surfaces often become rolling because of differential settlement, and electrical transmission poles...
Compaction Grouting as an Aid to Construction
The traditional use of compaction grouting has been to arrest settlement of existing structures, and occasionally to raise them back to their original grades. Recently, the process has...
Ground Modification for a 14-Story Structure Over a Deep Peat Deposit
The foundation design and construction for a 14-story reinforced concrete office building northwest of Minneapolis is described. The building's geometry provided unusual foundation...
Static Behavior of Piles in Cemented Calcareous Sands
A series of instrumented jacked model pile tests and another series of uninstrumented grouted model pile tests in a cemented calcareous sand were performed. The influence of pile installation...
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...
