Good Behaviour

This paper presents an experimental study on the behaviour of a braced steel frame with a proposed system: anticompression brace system (ABS) subjected to cyclic lateral loads. The ABS is proposed to deal with common brace buckling problems. In the study, split-K braced steel frames: with ABS and with ordinary brace system (OBS) were used as speciments. Cyclic loading tests were conducted to evaluate the performance of the proposed system in preventing the brace to buckle and to obtain the behaviour of the frame with ABS compared to the frame with OBS under cyclic quasistatic loading. From the cyclic tests, it was observed that the proposed system worked in preventing the braces to buckle, hence, the aimed state, “buckling prevention” was achieved. The results of the study also show that the frame with ABS had a lower initial stiffness compared to the frame with OBS, nevertheless, after exceeding drift ratio of 0.85% based on raw data or 0.64% based on fitted-curves, the frame with ABS exhibited good behaviour through lower degradations in stiffness and cyclic strength relative to the frame with OBS that experienced sudden and greater degradations.

Several traditional building group districts exist in Japan as a system for preserving the remaining historical villages and townscapes of the country, along with their surrounding environment. In the northern Kanto region of Japan, there remain examples of many dozo-style structures called “Dozo-dukuri,” forming a distinctive historical townscape. In the 2011 Tohoku Region Pacific Offshore Earthquake, the traditional townscapes and dozo-style structures of the Kanto region were seriously damaged. When restoring the walls of damaged dozo-style structures to a sound condition, demolishing and reconstructing all the mud requires considerable labor; moreover, few modern artisans can construct mud walls. However, if there was a method that could recover the structural performance of the walls immediately via partial repair, the restoration of the walls could again become economical. Therefore, in this study, we first surveyed the specifications of mud walls in the northern Kanto region. Then, we performed horizontal loading tests on full-scale walls produced according to the survey results to determine the structural performance of walls under a horizontal force, e.g., an earthquake. Further, a test specimen damaged by a horizontal force was repaired, and a horizontal loading test was performed again. The results elucidated the structural performance recoverability obtained by the proposed repair method.

The performance of beam-to-column joint panels of steel frames under horizontal loading is surveyed in elastic and plastic regions. Then the influence of shear deformation of those joint panels on the frame stiffness is investigated. It is found that the frame stiffness reduces remarkably when the yielding of joint panels takes
place. Taking into account these observations, a simple and practical design method of various shapes of joint panels is suggested.

This chapter describes major structures built from 1889 to 1904, many of which used skins of lightweight terra-cotta and glass that exploited new wind-bracing techniques and depressed glass prices to achieve unprecedented transparency. The flourishing of lightweight skins supported by rigid steel frames was uniquely permitted by Chicago's codes, which minimized the required thickness of masonry walls. Chicago's code helped architects and engineers solve the problems that continued to plague tall buildings on its poor soil. At 90 pounds per cubic foot for hollow brick and up to 140 pounds for pressed, the reduction of masonry envelopes from deep structural walls to thin veneers had immediate benefits. For instance, the six-foot walls of the Monadnock's first story weighed nearly a ton per running foot. Replacing this with a twelve-inch-thick wall of nonstructural hollow tile would have eliminated some 95 percent of the first-floor walls' dead weight.
