ABSTRACT Design and construction of artificial infrastructure on the lines of biomimicking principles requires the development of highly advanced structural systems which has the qualities of aesthetic expression‚ structural efficiency and most importantly geometric versatility. Diagrids‚ the latest mutation of tubular structures‚ have an optimum combination of the above qualities. In this paper‚ the peculiarities of the Diagrid‚ its structural behavior under loading and the design and construction

Shear‚ was appointed by the court to perform a forensic examination on the questioned message (the message provided by Mr. Munshani) and the comparative message (a second message from Mr. Trivedi found on Mr. Munshani’s computer).

The Kobe Earthquake‚ also known as The Great Hanshin Earthquake occurred January 17th‚ 1995‚ resulting in the second most deadly and most damaging Japanese earthquake of the 20th century behind The Great Kanto Earthquake of 1923. The epicenter was 20 km southwest of Kobe‚ with a moment magnitude of 6.9. Figure 1 shows the location of the epicenter with respect to the island of japan. The main ground shaking lasted about 20 seconds as a result of a right lateral strike-slip faulting system. A considerable

Soils below water tables are fully saturated. Soils belo tables are sat 2. All soils above water table are unsaturated. 3. Compacted soils are generally unsaturated soils. 4. Shear strength of a saturated clayey sand is greater than its unsaturated shear strength. Why do we need to understand

the thunderstorm. 2. How are tornadoes formed? Tornadoes form in unusually violent thunderstorms when there is sufficient instability‚ and wind shear present in the lower atmosphere. Instability refers to warmer and more humid than usual conditions in the lower atmosphere‚ and possibly cooler than usual conditions in the upper atmosphere. Wind shear in this case refers to the wind direction changing‚ and the wind speed increasing‚ with height. 3. Parts of a thunderstorm a) Updrafts/Downdrafts-

flow of the lower crust. The double set of extensional shear zones consists of an upper to middle crust collision and lower crust and upper mantle collision‚ which dipped in the opposite direction of the Mohorovicic-offsetting shear zone. These events caused crustal stretching of the lower crust and upper mantle. The upper to middle crust had extensional reactivation of the thrust as well as the formation of new extensional faults and shear zones. When the lower crust came into contact with the
