The hammers employed are to be of single-acting type for clay soil. Double-acting for sand and gravel soil. Alternatively‚ in the absence of a frame‚ hammer suspended from the jib of a crane can be used. A driving cap or anvil block is used as a protection against damage. In order

landslide or tidal wave ( tsunami). The earthquake becomes a dangerous phenomenon only when it is considered in relation with structures. Of course‚ the problem is the structure under seismic excitation and not the earthquake itself. This is because the structural system is designed basically for gravity loads and not for the horizontal inertia loads that are generated due to ground accelerations during an earthquake. Therefore‚ the earthquake has begun to become a problem or humans since they started building

Light wooden framed buildings were originally discovered when light partition walls were capable of forming a construction system by themselves. The system consists of timber studs frames assembled on site and tilted vertically or horizontally depending and what is needed. The idea was improved and accelerated with the availability of cheap mass produced nails and properly planed and cut pieces of wood. The first step to building a light timber platform building is to lay foundation walls to support

compressive strength. Due to such a low tensile capacity‚ flexural cracks develop at early stages of loading. In order to reduce or prevent such cracks from developing‚ a concentric or eccentric force is imposed in the longitudinal direction of the structural element. This force prevents the cracks from developing by eliminating or considerably reducing the tensile stresses at the critical midspan and support sections at service load‚ thereby raising the bending‚ shear‚ and torsional capacities of the

Executive summary The organizational structure of the current company was found to be a flat hierarchy with the departmentalization by function. New proposed structure is advised to be matrix with the functional and service divisions. Contingency models were used by: Joan Woodward‚ James David Thompson‚ Charles Perrow and Burns and Stalker. Models have explained the influence of the situational variables of task‚ technology and size on the creation of the new organizational structure. 1. Introduction

constructing and managing earthquake-resistant structures and facilities In developing the Structural Engineering Slide Library as a resource for teaching structural and architectural engineering‚ the topic of structural dynamics is of prime importance. Earthquake engineering is one of the most visible aspects of this field and one of the most easily illustrated due to the extent and variety of structural damage in earthquakes; thus it was decided to devote a volume to this subject.

Moral Frames & 2012 Election issues How is it that intelligent‚ rational‚ well meaning adults can look at the same set of facts on an issue and come to entirely different conclusions? The insight that George Lakoff had on this question in his book Moral Politics was that liberals and conservatives are viewing those facts through a moral framework where the facts are filtered and understood beyond rational thought. He identifies two main frameworks‚ related to parenting styles‚ for understanding

macro-sociological and micro-sociological theories‚ otherwise known as structural and action theories‚ respectively. As sociological theories‚ they both aim to explain the society we live in‚ but differ in where they choose to focus their explanation‚ with macro-sociological theories observing society as shaping the individuals that live in it‚ and micro-sociological theories observing individuals as shaping the society they live in. Structural theories explain society by looking at social structures‚ interactions
