Structures from first principles!
In 1879, inadequate design, ineffective supervision, poor workmanship, tight budget restrictions, time constraints and a general lack of understanding of the response of structures to dynamic forces from wind culminated into one of the deadliest structural failures of all time; the Tay Bridge collapse.
Inspection of activities on a site during construction is a very high-risk operation requiring expertise and experience. Site inspections are of paramount significance as they aim to minimize the risk of accidents arising within the construction site…
This article examines ways in which a structural engineer can identify the potentials for reuse and refurbishment of buildings at the early conceptual design stages
In 2007 under-engineering, inefficient regulation, ever increasing dead loads combined with inadequate inspections led to the deadliest structural failure in Minnesota’s history. The immediate aftermath saw an investigation board commissioned to probe the cause of the failure. The investigation would discover a systematic collapse in the very layers of defense the engineering profession creates towards preventing catastrophic failures
” An implicit assumption is an assumption that underlies a logical argument, course of action, decision or judgement that is not explicitly voiced nor necessarily understood by the decision maker1. In other words, implicit assumptions are those assumptions we make without even realizing it, hence they may go undetected.
While many engineers make the very valid argument that software prevent errors and human fallibility, many other engineers including this writer make the equally valid argument that these tools contribute to creating errors. Are these software’s actually aiding us to become better engineers or are they actually replacing us, at least, in cognitive sense, as engineers?
This article discusses the reuse, and refurbishment strategies adopted for the Triton Square building in London to enable the addition of three extra floors. Increasing the total floor area by 70% while achieving a SCORS A rating for the overall carbon per unit area for the scheme.
High above St. Lawrence River, on a hot sunny day in August, 1907, workers were working on the Quebec bridge when suddenly, the sound of twisting metals pierced the air, and the giant cantilever bridge under construction failed, crashing into the river with enormous force, such that people miles away in Quebec City believed an earthquake had hit.
Somewhere in Manhattan, a team of carpenters, welders and labourers were secretly working through the night, retrofitting steel connections under the directive of one of America’s finest Highrise structural designer, in a race to salvage the world’s 7th Tallest building. The skyscraper was meant to be a structural masterpiece but instead was poised to become one of the greatest engineering disasters of all time. Hurricane season was approaching and even a moderate storm would put the lives of over 200k people at risk
Just as there are dangers with the use of software in engineering, it is equally important that we also note that there are also dangers with non-automation. In this article, we’ll look at the circumstances in which the virgin galactic plane crashed in 2014 and if there are lessons that can be learnt.
