Engineering the Envelope: Structural Load Assessment for Facades
Identifying, Quantifying, and Combining Every Load That Acts on a Façade — From Self-Weight and Wind to Impact, Thermal, Seismic, and Maintenance Loads
Course Description
A façade is not a passive skin — it is a structural assembly. It resists wind, absorbs thermal movement, deflects impacts, and supports maintenance equipment, all at once, for decades. This comprehensive technical CPD course provides architects and building design professionals with a complete map of the loads and environmental actions that act on a façade — the starting point of every façade calculation, because every number in a bracket, mullion, or glass check traces back to a load.
You'll learn to trace dead load paths from the outermost panel to the primary structure, understand where wind loads peak and why, apply the three separate barrier checks correctly, and recognise which items on the load list are genuine loads and which are movement demands the façade must follow rather than resist. The course covers impact testing, climatic loading of sealed glass units, seismic drift, snow and ice, maintenance and construction-stage loads, and the load combination philosophy behind ultimate and serviceability checks.
Presented by Eugene Korch (façade engineer and IAST Programme Director), the course uses worked examples and real project situations to show how the most commonly missed loads — internal wind pressure during construction, funnelling between buildings, snow drift, maintenance point loads, ponding on blocked canopies — lead to undersized brackets, broken glass, and failed fixings.
Combining a complete load checklist, sign-convention rules, and worked combination examples, this course is designed to help you confirm, for every project, which loads apply, which do not, and what the worst combination looks like — before anything is sized.

Learning Outcomes
By the end of this course, you will be able to:
-
Distinguish non-load-bearing, self-supporting, and load-bearing façades — and understand why this course deals with systems that carry only their own weight and environmental loads
-
Trace the dead load path of any façade system from the outermost element to the primary structure, including every secondary component that adds weight
-
Estimate glass weight using the thickness rule of thumb and recognise the risk of sizing brackets from a preliminary glass build-up
-
Understand where wind loads peak on a building — corner and edge suction, flow separation, and why loaded area changes the pressure coefficient
-
Combine external and internal wind pressure with the correct sign convention and recognise the classic two-negatives error
-
Identify wind situations the base tables do not cover — funnelling between buildings, complex forms, and construction stages with dominant openings
-
Apply the three independent barrier checks of BS 6180 — line load at 1100 mm, distributed load on the infill, and point load — together with the vertical load
-
Distinguish soft body, hard body, and pendulum classification testing, and know which test applies to the installed element and which to the glass product
-
Understand why sealed insulated glass units are the one case where temperature creates a genuine load rather than a movement demand
-
Recognise seismic inter-storey drift, wind sway, and thermal movement of framing as movement demands accommodated at the connections
What's Covered
Introduction: Every Façade Carries Load
Why a façade is a structural assembly, not a passive skin.
Non-load-bearing, self-supporting, and load-bearing façades — and the load-bearing inner leaf exception.
Progressive collapse and the Ronan Point lesson.
Dead Load
Self-weight of everything permanent — panels, framing, brackets, insulation, membranes, gaskets.
Load paths by system: rainscreen, stick curtain wall, precast, masonry cladding.
Stacked versus hung support — how the weight reaches the bracket.
Material densities and the glass thickness rule of thumb.
Common errors — forgotten secondary elements and the preliminary glass build-up trap.
Wind Load
Positive pressure, suction, and where the highest loads occur.
Terrace paving on pedestals — the façade responsibility nobody expects.
The calculation chain from basic wind speed to element force.
Pressure zones, the parameter e, and why Zone A takes the worst suction.
Loaded area and the two pressure coefficients.
Internal pressure, the sign convention, and the classic combination error.
Dominant openings during construction.
Funnelling, complex forms, and when wind tunnel studies are needed.
Why single elements are designed statically — and the slender exceptions.
Barrier Loads and Crowd Loading
Where barrier loads apply — balustrades, spandrels, and floor-level glazing.
Three separate checks: line load at 1100 mm, distributed load, point load.
Vertical loads on barriers and crowd loading on terraces and walkways.
Impact Loads
Soft body and hard body impact on the complete installed element.
The pendulum classification test and the three-part breakage code.
Glass barriers — staying in place after breakage.
Thermal Effects
Design surface temperature versus air temperature.
Movement from the installation temperature to each extreme.
Differential movement between aluminium, steel, and concrete.
Climatic loading of sealed insulated glass units — temperature, altitude, and gas type.
Thermal stress breakage of glass.
Seismic Effects
Inter-storey drift as a movement demand.
Life safety and damage limitation — rocking connections, stack joints, ductile fixings.
Snow, Ice, and Rain
Snow on canopies, sills, louvres, and sloped glazing.
Drift zones at parapets, setbacks, and re-entrant corners.
Icicles over pedestrian areas.
Ponding on blocked canopies — when water outweighs snow.
Maintenance and Access Loads
Cradle suspension loads and rope access.
Walkway and point loads at unpredictable positions.
The installation stage — panels without neighbours, stacked materials, erection wind limits.
Blast, Acoustic, Moisture, and Fire
Blow-out panels and the blast consultant's role.
Acoustic fatigue near airports and plant.
Irreversible brick expansion, freeze-thaw, and corroded fixings.
Fire temperatures, aluminium strength loss, and mandatory replacement after fire.
Load Combinations and Design Philosophy
Ultimate versus serviceability — will it break, or will it deflect, leak, or look wrong.
Combination coefficients and the leading action.
A worked mullion check both ways and a roof panel combination example.
Understanding what each check protects against.
Load Application
Tributary areas — a worked mullion example.
Point loads, line loads, and surface pressures from the same physical load.
Bracket eccentricity on highly insulated façades — the backpack analogy.
Summary and Checklist
The complete load list and the most commonly missed items.
Loads versus movement demands.
The project checklist — from load review to sign convention.
