Built to Resist Earthquakes The Path to Quality Seismic Design and Construction Briefing Paper 1 Briefing Paper 1 Building Safety and Earthquakes Part C Earthquake Resisting Systems Introduction This Briefing Paper 1 Building Safety and Earthquakes consists of four parts describing earthquakes and their effects on buildings Parts A and B describe the causes of earthquakes and resulting ground motions and explain how earthquake motions create various forces acting on a building This Part C describes the types of structural systems and lateral force resisting elements used in buildings and how they can be used in combinations Part D discusses the load path of earthquake forces within buildings Structural Systems Defined The Uniform Building Code UBC earthquake provisions define three basic types of building structural systems bearing wall systems building frame systems and momentresisting frame systems Bearing wall systems consist of vertical loadcarrying walls located along exterior wall lines and at interior locations as necessary Continue to download »

EARTHQUAKE RESISTANT HOUSING A Wood Frame Building Performance Fact Sheet One of the proven features of Canadian woodframe construction is its excellent life safety performance in earthquakes Compared to other forms of house construction a platform frame wood house is one of the safest places to be in a quake In the past fifty years our understanding of the risks posed by earthquakes and our ability to survive them have improved But at the same time soaring populations and growing urban densities have increased humanity s earthquake risk An earthquake is a sudden release of energy from the motion of geologic plates Some parts of the world such as the west coast of North America are high risk areas Buildings there must resist strong earthquake forces These forces depend on the strength of the quake how far away it originated what type of geological event caused the earthquake and the geology immediately adjacent to a given building Each structure with its own unique set of characteristics such as stiffness and strength reacts differently to earthquake 
CHAPTER 1 Introduction to Financial Modeling W hat is a financial model What is the difference between a financial model and the spreadsheet solutions you create or VBA programs you write all the time to answer financial questions or solve financial problems A simple practical answer is that a financial model is designed to represent in mathematical terms the relationships among the variables of a financial problem so that it can be used to answer what if questions or make projections Some of the spreadsheet solutions that people create capture some of these relationships as well and therefore can answer what if questions to some extent But because they are not primarily designed with these objectives in mind they do not try to capture as many of these interdependencies as possible and their structures often make it cumbersome to answer what if questions or make projections with them This may sound a little abstract So let us look at a simple concrete example Suppose you are using a spreadsheet to calculate based on your taxable income what your after tax

A bolt having one end in the form of a hook hydraulic gradient A line which represents the relative force available due to the potential energy available This is a combination of energy due to the height of the water and internal pressure In an open channel the line corresponds to the water surface In a closed conduit if several openings are placed along the top of the pipe and open end tubes inserted a line connecting the water levels in the tubes represents the hydraulic grade line hydraulic jump Transition of flow from the rapid to the tranquil state A varied flow phenomenon that produces a rise in elevation of backwater flow surface A sudden transition from supercritical flow to subcritical flow conserving momentum and dissipating energy hydraulic radius The cross sectional area of a stream of water divided by the length of that part of its periphery in contact with its containing conduit the ratio of area to wetted perimeter horizontal ellipse A long span corrugated steel structure with the major diameter horizontal hydraulics That branch of science or
