Glass Guardrails Failures – Lessons Learned

March 10, 2021
5:30 PM - 7:30 PM

Online Meeting

PRESENTERS:
DAVID SCHNERCH, Ph.D., P.E., Associate Principal with WJE has completed a wide range of failure investigations, structural evaluations, load tests, and repair designs of buildings, bridges, parking garages, and other structures.
EMMA CARDINI, P.E., Associate Principal with WJE has experience in façade investigations, historic preservation, and structural condition assessments.  

DESCRIPTION:  Glass guardrails at roof terraces and balconies have a safety function while not obscuring views that are desirable for high rise towers.  Frequently loading on the guardrails is governed by wind loads rather than the code requirements for a building occupant leaning on the guardrail.  In order to resist these loads without posts, a base connection that transmits loads to the structure and minimizes rotation is required.  Frequently these critical connections are subject to installation and durability issues.  This presentation describes design loads for guardrails, thermal expansion properties, design considerations, some of the maintenance issues with various types of systems and discusses potential durability issues.
