Japan Studies Floating Airport (Available only in Structural Engineering Special Issue)
Floating airport structures are being studied in Japan. Because of a severe shortage of land, the Japanese and U.S. governments are considering floating structures for civilian and military...
Stabilizing the Stacks
Spenser White and Prentis designed a hybrid soil nailing system to ensure that a historic library on the Bryn Mawr, Pennsylvania, campus would not be damaged during adjacent construction...
Two- and Three-Dimensional Hydrodynamic Modeling of the Salton Sea, California
The Salton Sea, the largest surface water body in California, faces a myriad of problems related to rapidly changing water levels, rising salinity, accelerated eutrophication, fish kills,...
Seismic Design Doubles Lateral Resistance (Available only in
A veterans hospital in Palo Alto, Calif. had to be built under severe design constraints. The seismic code for hospitals is among the most stringent of codes and this facility was sited...
High Over Shanghai
In response to difficult design conditions, Shanghai's Jin Mao Tower's structural system harmoniously mixes building materials and strategically places them to...
Wave Forces on Inclined and Vertical Wall Structures
This monograph,
Space Station Microgravity Analysis and Assessment
The space station will be a platform for microgravity research. For superior microgravity science, the experiment locations must experience very little acceleration in the quasi-steady...
Microgravity Research in a Space Station Environment
A broad class of scientific experiments have evolved which utilize extreme low acceleration environments. A space station can provide such a `microgravity' environment, in conjunction...
Wheel Space Station for 2025
The advantages and disadvantages of three basic space station designs are discussed. These designs are a zero-gravity can like Skylab, a tethered system, and the wheel. A design of a wheel...
The Effect of Zero Gravity on Bones
Zero-gravity has created many problems for astronauts and researchers in space. Calcium depletion is cited as a major health problem. There are many different theories as to why zero-gravity...
Bridge Rail Impact Forcing Functions
Bridge rails are designed according to AASHTO standards with a static 10-kip (44.5 kN) lateral load. The computer programs BARRIER VII and COSMOS are used to determine the deflections...
Composite Walls as Shear Elements in Tall Structures
This paper describes a system of composite walling that can be used as a lateral load resisting system in tall structures. The composite walling comprises two skins of profiled steel sheeting...
Progress in Reinforced Concrete Column Design
This paper reviews some of the design procedures used for both braced and unbraced frames constructed in reinforced concrete. The discussion refers to the problems of material and geometric...
Hurricane Windspeeds at Inland Locations
A critical review of the windfield and filling models used in the hurricane simulation procedure of Batts et al. [1980] clearly indicates that the hurricane windspeeds they obtained for...
Lateral Load Resisting Systems for Circular Buildings
The design of structural systems to economically limit inter-story drift and building acceleration for circular high rise buildings is presented within the framework of two recently constructed...
Criteria for Acceptable Wind-Induced Motions
This paper discusses criteria for evaluating acceptable wind-induced building motions. The paper draws on the results of moving room experiments and the performance of actual buildings...
Methods to Control Wind-Induced Building Motions
The wind-induced response of tall buildings can be controlled by global design modifications that can be placed in three broad categories, namely, design changes in structural systems,...
Uniform Lateral Load Capacity of Infilled Frames
Three tests were conducted on 2.4 meter by 2.4 meter steel frames infilled with structural clay tile to determine the behavior and capacity when subjected to uniform lateral loads. An...
Dynamic Testing of Unreinforced Brick Masonry Infills
A significant seismic hazard may exist when unreinforced masonry infill panels fall out of their surrounding frames as a result of excessive accelerations applied normal to their plane....
Damping Systems for Controlling Wind Induced Motions of Structures
This paper presents the state-of-the-art in damping systems for controlling wind induced motion of structures and their applications in the U.S. and Japan. Both passive and active systems...
