Velux, a global roof-window company, thinks the future is looking up, literally, as the proximity of houses with side windows brings unwelcome views and a lack of privacy.
The peak global drift at roof level was 166 mm, and the peak inter-story drifts were approximately 1.3%.
Local (member rotations) and global (interstorey and roof drifts) deformations were employed to compare the inelastic response of the retrofitted frames.
The global drift at roof level was approximately 0.25 meters and maximum inter-story drifts were approximately 2% for the floor average with individual wall drifts reaching just over 3% in one corner of the building at the fifth story.
To analyze the impact of a change in the reflectivity of city roofs, scientists with Lawrence Berkeley National Laboratory (LBNL) and the state of California estimated the global number of roofs and asphalt surfaces in cities.
There were never more global leaders under one roof than here in Paris at the global climate negotiations on Monday.
Cranes are busy building housing next door (which, although partly funded by Facebook, the company insists is not the rumoured "Zeetown" for its workers), while volunteers set up marquees on the roof for "global causes day", an annual charity initiative.
Central ring and circular purlins are used, where strengthened purlins act as ring hoops to increase the roof's global stiffness and reduce horizontal forces on the top of the columns.
(3) Global and direct irradiations on roofs are highly correlated with roof aspect and slope, with high global and direct irradiations observed on roofs of aspect 100 250° and slopes of 0 60°, whereas diffuse irradiation on roofs is only affected by roof slope.
Uranium prices are going through the roof on a global atomic revival.
The global base shear force versus roof lateral displacement hysteretic response is plotted in Fig. 21 for the BF475 and BF975 tests.
