Two of the main financial benefits of post-tensioning is the reduction in slab thickness and rebar compared to non-prestressed slabs. The downside side of this reduction is post-tensioned structures can...
In concrete members, shear friction is considered for any interface between two concretes cast at different times, between dissimilar materials, as well as for any existing or potential crack. For...
This webinar will cover common structural challenges faced during plan review. Issues related to coordination between various design professionals, plan revisions required midway through the approval process that may impact...
During this seminar, Ian McFarlane will discuss design of mat foundations and soil-structure interaction. The session will describe the uses of mat foundations, historical perspectives that have led to the...
Multi-story light-frame structures are often built atop concrete podiums, and in areas of high seismicity the overturning restraint system used to secure shear walls in these buildings can produce very...
It has long been recognized that the seismic response of one-story tilt-up concrete wall buildings (and similar buildings with flexible diaphragms and rigid vertical elements) is controlled by the flexible...
This web seminar will provide step-by-step hand calculations for the design of a typical two-way flat slab that is commonly used for a multitude of building applications ranging from parking,...
Part 1 will cover structural design fundamentals for a variety of retaining wall types. It will address fill walls, such as cast-in-place concrete cantilevered walls and mechanically stabilized earth walls;...
Part 2 will focus on cast-in-place concrete cantilevered wall design, and will go into greater detail than Part 1. It will go through examples of design calculations, step-by-step, for both...
This webinar will focus on wind provisions of ASCE 7/ IBC that are frequently misunderstood or incorrectly applied, including building enclosure classification, torsional wind design, and wind load analysis methods....
