Cantilevered laminated glass balustrades: the Conjugate Beam Effective Thickness method—part I: the analytical model

By: Adam Nizich, L. Galuppi
The proper assessment of shear coupling is necessary for the evaluation of laminated glass performance between the bounding layered and monolithic limits. The most common simplified design approach consists in defining the effective thickness, i.e., the thickness of a monolithic section with equivalent flexural properties.

Glass spandrels and shadow boxes: Design and construction considerations

Glass spandrels are a common design strategy used to opacify floor levels in building facades. These opaque glass assemblies are integrated into glazing systems, such as glass curtain walls or window walls, to provide visual continuity with adjacent vision glass to render an all-glass look to the building facade.

Multi-Unit Residential Construction Over Podiums

Multi-unit residential construction continues to see an increasing prevalence of “five-over-one” stick-built framing systems wherein the superstructure of residential units are supported on a podium structure above parking, retail, amenities, or all-of-the-above. While the design focus is typically on the efficiency of the residential units or to maximize the height of stick-built construction, due consideration is required for a properly designed, detailed, specified, and constructed podium structure.

Evaluation of the Floor Acceleration Response Spectra of Numerical Building Models Based on Recorded Building Response Data

By: Ricardo Medina, H. Anajafi, C. Adam
The recorded floor acceleration responses of a wide variety of instrumented buildings are used to evaluate the findings of previous numerical studies regarding the effect of different parameters on the seismic response of nonstructural components (NSCs).

Assessing Critical Infrastructure Reliability for Unseen Data Center Facility Risk

Critical businesses – from finance and networking to water and electric utilities – have robust digital infrastructure systems that rely on a vast network of data centers and internet exchange hubs to deliver essential online services. These facilities can be housed and managed on site or outsourced to external colocation centers, and vary greatly in size and complexity. Our reliance on these digital backbones to underpin business services is rapidly expanding across all sectors of daily life. In today’s technology-driven world, a business’s financial well-being depends on the continuous operation of these facilities’ assets – triggering significant investment to maximize digital infrastructure reliability and downtime.

Cyclical Testing of Flat Lock Copper Seams

The use of flat seam copper roofing in the US dates back to Paul Revere’s copper installed on the Massachusetts State House in 1802. Since then, flat seam copper has been widely used in low-sloped roofing applications as it is a reliable, durable roofing material; history shows that flat seam copper roofing can provide a service life of 100 years, which the original State House roof achieved. However, flat seam copper roofing is only as reliable as the quality of the seams between panels.
