CHAPTER 1 INTRODUCTION The seismic force-resisting system of a building structure is composed of vertical elements‚ horizontal elements‚ and the foundation (Fig.1.1). The vertical elements extend between the foundation and the elevated levels‚ providing a continuous load path to transmit gravity and seismic forces from the upper levels to the foundation. The horizontal elements typically consist of diaphragms‚ including collectors. Diaphragms transmit inertial forces from the floor system to the

PORTERS 5 FORCES Suppliers: Here you assess how easy it is for suppliers to drive up prices. The fewer the supplier choices you have‚ and the more you need suppliers’ help‚ the more powerful your suppliers are. Buyer Power: Here you ask yourself how easy it is for buyers to drive prices down. This is driven by the number of buyers‚ the importance of each individual buyer to your business‚ the cost to them of switching from your products and services to those of someone else. Industry Rivalry:

How to Do an Axel The process which leads to a successful axel may comes easily to some people and not to others. First‚ make sure your skates are tight and that your ankles don’t move around inside. Second‚ warm up by skating a couple laps around the rink so that when you start jumping there will be less chance of getting an injury. Then‚ practice springing straight into the air and landing on one skate. Now‚ begin going through the motions of the axel by first pulling your arms back behind you

Of Mice and Men is a novel about power and status. What does the novel reveal about American society at this time? There are a couple of ways of answering this question. You could go through some of the major characters and think about the way the hard times are reflected through their actions and behaviour. For Example Curley’s Wife wants to escape‚ she thought marrying Curley was a form of escape. In fact it just turned out to be a different trap. All the other men treat her badly
