Equivalent Static Method and Response Spectrum Method in Seismic Analysis

In seismic analysis of structures, Equivalent Static Analysis and Response Spectrum Analysis are two methods that analyze the elastic behavior of a structure, in other words, the behavior of the structure without considering any yields (plastic hinges). But how do they differ? Equivalent Static Analysis is the simplest most straightforward analysis, which will either suffice […]

Benefits of Green Roofs

In this post we will discuss one of the most environmentally friendly construction concepts, green roofs. The benefits of green roofs are so many that it is difficult to understand current policies being inadequate to support (or even mandate) this system, including in developed countries – of course there are incentives or certain programs that […]

Choosing and applying suitable grouting method

Grouting is one of the most common ground improvement methods, which can be applied in various ways for different situations. In this post we will look at grouting methods, try to explain when to chose which method and certain common issues that may be encountered.

Strut and Tie Method

This is a very useful method, which is also allowed by AASHTO or bridges and ACI 318 when designing concrete bridge and building structures respectively. By making use of this method, the stresses especially in members such as deep beams can be more realistically represented. The struts here represent the imaginary compression members of a […]
