Tactile-Guided Vision-Impaired Friendly Footbridge per EC3, AWS D1.5 & AS 5100 Urban

Steel footbridges are lightweight bridges designed specifically for pedestrians, bicycles, and light service vehicles, with a clear deck width of 1.5–3.0 meters and a live load of 4–5 kN/m². Their core design is guided by human subjective experience rather than ultimate load-bearing capacity, with particular attention needed for controlling vibration, slip resistance, and visual transparency. The structure can utilize trusses (transparent), plate girders (simple), or arches (landmark), serving as a key component of urban slow-traffic systems and park landscapes.

2.Product Highlights

l Luminous Handrails: The surface of the handrails is coated with light-storing luminous paint, absorbing light for 10 minutes to glow for 8 hours, guiding evacuation during power outages.

l Integrated Drainage Bridge Deck: Steel plate stamped diamond grating (35% open area) allows rainwater to drain directly, leaving the bridge deck free of standing water.

l Plug-in Railings: Posts are inserted into edge plates and fixed with spring locks, requiring no bolts; replacement takes only 2 minutes per post.

l Shock-Absorbing Rubber Pads: 20mm thick natural rubber pads are embedded at the supports, increasing damping ratio to 5% and reducing foot impact.

l Bird-Proof Roof Spikes: The enclosed corridor roof comes pre-installed with stainless steel anti-bird spikes (100mm spacing) to prevent birds from roosting.

l Integrated Tactile Paths: Raised strip or circular tactile patterns are directly molded into the bridge deck, eliminating the need for separate ceramic tactile tiles.

3.Product Materials

ü Main Structural Materials: Adopt high-strength low-alloy structural steel, weathering steel and austenitic stainless steel as the main load-bearing materials, with excellent tensile strength, toughness and fatigue resistance, ensuring the long-term stability of the bridge structure. Among them, weathering steel can form a stable protective rust layer in the natural environment, further improving the corrosion resistance of the structure.

ü Anti-Corrosion Protection Materials: Use hot-dip galvanizing, high-performance anti-corrosion paint system, powder coating and cathodic protection technology as the core anti-corrosion means. The hot-dip galvanizing layer can provide long-term physical barrier protection for the steel substrate, and the topcoat can further enhance the weather resistance and decorative effect of the structure.

ü Supporting Functional Materials: The deck adopts anti-slip and wear-resistant polymer paving materials, which have excellent anti-slip performance in rainy and snowy weather; the structural joints use high-strength bolt fasteners and elastic damping pads, which can effectively absorb structural vibration and adapt to thermal expansion and contraction deformation; the handrail and guardrail parts use stainless steel or galvanized steel pipes, which have both safety and decorative properties.

4.Design Features

Ø Frequency Separation Principle: Vertical fundamental frequency ≥ 3Hz (walking), horizontal ≥ 1.5Hz, to avoid resonance with walking frequency.

Ø Differential Settlement Adaptation: Bearings at both ends of the corridor allow ±15mm independent settlement, achieved through spherical sliding bearings.

Ø Glass Wind Pressure Resistance: Enclosed glass side walls designed for 1.5kPa wind pressure, PVB film thickness ≥ 1.14mm.

Ø Lifetime Anti-Slip Guarantee: Polyurethane paving contains corundum aggregate, can be recoated after wear, anti-slip performance does not deteriorate.

Ø Hidden Thermal Expansion and Contraction Joints: Bridge end expansion joints ≤ 30mm, covered with rubber strips for a neat appearance.

Ø Embedded Pipeline Channels: Hollow railing posts (φ50mm or more), filled with fireproof sealant after wiring.

5.Core Advantages

⭐Maintenance-Free Hangers: Uses inverted V-shaped diagonal braces instead of vertical hangers (mid-support type), no risk of fatigue fracture.

⭐Weld-Free Assembly: Fully bolted, plug-in connections, no hot work on site, reduced fire rating requirements.

⭐Variable Light Transmission: Adjustable ceiling louvers (0–90°), sun shading in summer, daylight in winter.

⭐Self-Sliding Snow Load: Smooth curved arch surface, accumulated snow spontaneously slides off under gravity (slope ≥ 25°).

⭐Anti-Graffiti Coating: Railing surface with fluorocarbon paint and oil-repellent layer, spray paint graffiti can be removed with solvents.

⭐Automatic Post-Earthquake Reset: Podium rubber bearings have self-resetting function, corridor returns to original position after an earthquake.
