Modular Robots for Making and Climbing 3-D Trusses
A truss climbing robot has been extensively investigated because of its wide range of promising applications such as construction and inspection of truss structures. It is designed to have degrees of freedom to move in three-dimensional truss structures. Although many degrees of freedom allow the robot to reach various position and orientation, it causes complexity of design and control. In thi...
متن کاملPeriod Formulas for Moment-resisting Frame Buildings
Most seismic codes specify empirical formulas to estimate the fundamental vibration period of buildings. Evaluated first in this paper are the formulas specified in present US codes using the available data on the fundamental period of buildings “measured” from their motions recorded during eight California earthquakes, starting from the 1971 San Fernando earthquake and ending with the 1994 Nor...
متن کاملModular specification of frame properties in JML
ion. The only restriction is that the field names of the dependees must be specified in the depends clauses. 5.1.2.2. Locality Rule. The locality rule is fairly natural: Usually, abstractions of dynamic components abstract from the states of their interface and representation objects. As long as these objects are reachable from an interface object via read-write references, such abstractions me...
متن کاملThe Effect of Local Damage on Energy Absorption of Steel Frame Buildings During Earthquake
Progressive collapse is a kind of failure in which whole or large part of a structure collapse when a local damage occurs and distributes to other parts. Many researchers focus on the column removal analysis and study of the structure behavior under effect of gravity loads, so these investigations are mostly carried out on the tall building. Earthquake inspections indicate structural element ca...
متن کاملModular server frame with robust earthquake retention
Adequate retention of computer systems during earthquake events is important because it can not only prevent human injury and potential system damage, but also ensure system availability by limiting to acceptable levels the transmitted accelerations to critical system components such as hard drives. This paper discusses the design of an IBM frame structure and related hardware, and the retentio...
