Fundamentals of Prestressed Concrete Bridge (with solved example)

pretensioning

Fundamentals of Prestressed Concrete Bridge (with solved example) Introduction: In prestressed concrete, a prestress force is applied to a concrete member and this induces an axial compression that counteracts all, or part of, the tensile stresses set up in the member by applied loading.  In the field of bridge engineering, the introduction of prestressed concrete … Read more Fundamentals of Prestressed Concrete Bridge (with solved example)

Measuring Earthquakes | Measuring Earthquake

Seismographs record earthquake events

Measuring Earthquakes The power (magnitude) of an earthquake is measured on the Richter scale, using an instrument called a seismometer.The Richter scale is numbered 0-10 with 10 being the most powerful. The Richter scale is logarithmic – an earthquake measuring 7 is 10 times more powerful than one measuring 6 and 100 times more powerful … Read more Measuring Earthquakes | Measuring Earthquake

Earthquake Effects on Tall Buildings

Earthquake Effects On Tall Buildings Types of Earthquake Faults Only convergent and transform boundaries tend to cause large earthquakes. Divergent boundaries do cause earthquakes as well, but these tend cause much less  damage. Convergent boundaries are mostly found just offshore of many continents, where an oceanic plate subducts beneath a continental plate Most of the … Read more Earthquake Effects on Tall Buildings

Advanced Earthquake Resistant Design

Advanced Earthquake Resistant Design Introduction Whenever there is an earthquake related disaster in the news with collapsed buildings &other structure all over the place, one may think that earthquake resistant design(EQRD) of structure are still in dark age. Thus we desperately need advanced earthquake resistant design to make structure less vulnerable to earthquake even for … Read more Advanced Earthquake Resistant Design

Introduction to Structural Concepts and Design

Structural Concepts and Design

Introduction to Structural Concepts and Design •Concrete design in Australia follows AS 3600; •Concrete behaviour varies depending on whether it is in tension or compression; •The strength of concrete is given in terms of the characteristic strength; •Characteristic strength is defined in AS 3600 as “the value of material strength, as assessed by standard test, … Read more Introduction to Structural Concepts and Design
