Shake table tests were conducted to examine the seismic performance of unit houses (prefabricated metal houses). The specimens comprised 4 unit-house units connected vertically and horizontally. After experiencing JMA Kobe record twice, welded connections at base beam had fractured, local buckling occurred in some beams. Bolted beam-to-column dissipated substantial energy by slipping repeatedly...

Fire sprinkler systems damaged during earthquakes can compromise building functionality either by loss of fire protection and/or flooding damage. To characterize the seismic behavior piping systems, shake table tests were conducted on a specimen with features representative actual practices in New Zealand. The was subjected to set motions including recorded floor acceleration response histories...

Increasing the population, urbanization has led to the rapid construction of buildings. Due to space constraints and an increase in land cost, these buildings are built too close to each other and can cause damage under dynamic actions such as earthquakes. A new technique, known as Structural coupling, has been developed recently, has found very effective in dissipating the dispersive vibration...

The objective of this study is to design a robust direct model reference adaptive controller (DMRAC) for a nonlinear cardiovascular model over a range of plant parameters representing a variety of physical conditions. The direct adaptive controllers used in thisd study require the plant to be almost strictly positive real (ASPR) that is, for a plant to be controlled there must exist a feedback ...
