Modern structures often demand high performance façades that can be reliably installed in a minimum time period to meet tight construction schedules.
Curtain wall façades are one of the façade systems increasingly selected
HALFEN Cur ta in wal l sys tem
by architects and their clients. Curtain walls can be constructed in a variety of materials - glass, metal or stone - sup-ported by a steel or aluminium frame. The frame can be either pre- assembled in a factory as a fi nished element or assembled on-site immediately prior to installation to the main structure.
To maximise effi ciency and reliability in installation, HALFEN Cast-in channels and HALFEN T-bolts are often the pre-ferred method selected for connecting façade elements to a building’s super-structure.

Welding is slow, is a fi re risk, and needs to be closely monitored to ensure quality.
Welding requires moving heavy equipment and also requires a costly energy supply.
Advantages of HALFEN Cas t - in Channels Compared to Dr i l led and Welded Connect ions
Vibration can also cause permanent health damage.
• power tools cause vibration, noise and dust work-safety hazards and reduced available installation time
• additional drilling required if adjustment is needed after ini-tial installation slower installation, drilling
• on-site check for installation quality is unreliable (depth of hole, hole diameter, critical torque) higher risk
• drilling costs time and bolt installation requires further tests to verify quality slower installation
• heavy electrical equipment, trailing cables and electricity safety hazards
• drilling and the expansion forces from installed bolts may damage concrete and reinforcement higher risk and po-tential high repair costs
• sparks from welding can start fi res and damage glass and aluminium façades high risk and high cost
• quality welding is diffi cult to achieve and verify on site increased uncertainty
• welding takes time and requires testing to verify quality slow installation and increased uncertainty
• heavy electrical equipment, trailing wires and electricity safety hazards
• subsequent adjustment requires welds to be broken and re-welded slow installation
• cast-in plates are designed per project and require testing to verify performance
• requires post-welding corrosion protection poor corro-sion protection, time consuming checking for damage to façade from dripping paint; hazardous to health

Given:
Working loads on the curtain wall bracket:- working dead load (gravity) Fg = 6.00 kN- working wind load Fw = 12.00 kN
The calculation example uses load and resistance factor design,applying partial safety factors F on the load side (action).
for dead loads: F = 1.35 (acc. to German standard DIN 1045-1 )for wind loads: F = 1.50 (acc. to German standard DIN 1045-1 ) - design dead load Fgd = F × Fg = 1.35 × 6.0 kN = 8.1 kN- design wind load Fwd = F × Fw = 1.5 × 12.0 kN = 18.00 kN
Design forces, acting on the channel:
NEd ≙ BVd = (Fgd × 70 + Fwd × 30) / 130 = (8.1 × 70 + 18.0 × 30) / 130 = 8.51 kN Vy,Ed ≙ BHd = Fwd = 18.0 kN

HALFEN Software HTA-CEHALFEN Software
Although HALFEN Cast-in channels could previously be selected from tables according to their load bearing capacity, the ETA requires a wider range of veri-fi cations for cast-in channels in combi-nation with the selected concrete. These verifi cations are processed by the user-friendly HALFEN software; in just a few seconds the user has a list of suitable HALFEN Cast-in channels for the relevant load situation.
Boundary conditions
The calculation takes into account all necessary boundary conditions, typical examples being:
• cracked or non-cracked concrete
• the concrete components geometry, in particular the distances of the channel to the component edge
• various reinforcement layouts
• consideration of several dimensions or characteristic loads
• loads positioning with a defi nable adjustment range, and the option of moving the defi ned bolt layout along the complete channel length
• verifi cation of the required HALFEN T-head bolts and if required also for stand-off installations
• engineering consideration of fatigue loads and fi re infl uence
The HALFEN Cast-in channel calculation program is based on ETA-09/0339 (European Technical Approval) and CEN/TS 1992-4 (Design standards of anchorages for use in concrete); the program provides the user with a convenient and very powerful calculation tool.

Channel load data
Fastener in format ion
A series of three tests produced the following average ultimate loads:
The adjacent load deformation diagram can be used to determine allowable loads based on acceptable displacement and the required safety factor according to local building codes. The diagram is based on the following:• A concrete slab ≥ 125 mm thick and reinforced according to the
diagram on the previous page.• Concrete compression strength ≥ C 20/25 N/mm² (cylinder/cube)
with normal weight aggregate.• Load equally distributed to the channel via two HALFEN T-bolts
(ordered separately) spaced at ≥ 150 mm centres. See below for sizes and load capacities.
A typical calculation method is shown below. The factors used in the calculation example are just an example. Actual factors used on a project basis must be checked according to local or national building regulations. These calculations also make no allowance for load increase due to load eccentricities. These must be included according to the project design of the connection. Contact us if further information and help is required here.Calculation example: Assumed safety factor 3 applied to the ultimate test load.
HALFEN T-bolts type HS 50/30 8.8 grade, M16 and M20 suitable for the required load are recommended for use with HALFEN Cast-in channel HCW 52/34. The loads FS allow., see table below, are per bolt and based on applied safety factors of approximately 2.5 : 1; other factors may be applied accor-ding to appropriate regulations and project requirements.
Please note that fastener performance may be limited by channel capacity. The sizes shown result from salt spray tests with a special coating equivalent to hot-dipped galvanization. T-bolts in other sizes and materials are available if required. Please contact us for more details.

Edge of S lab Brackets HCW-ED / -EW
HALFEN Edge of slab brackets are connected in pairs toeither side of the mullion and are available in two types:• HCW-ED brackets are designed to support both vertical
and horizontal loads.• HCW-EW brackets are designed to support horizontal wind
loads only.
The brackets connections are easy to adjust.T-head bolts M12 grade 8.8 connections are required for the mullion and cast-in channel. Pilot holes are also provided in the bracket if it is preferred to temporarily position the bra-cket prior to drilling the mullion for the main connection.
The brackets are manufactured from high strength alumini-um. Nylatron shims are available as low-friction shims for windload brackets.HCW-ED brackets are marked ‘R’ (right) and ‘L’ (left) with ‘UP’ at the top. Care should be taken to orientate the bra-ckets correctly to avoid overloading the connections.

Des ign Windloads for Brackets Type HCW-EW, Forces at the Bol t for HCW-ED
Calcu lat ion bas isDes ign windloads for type HCW-EW
To calculate the reaction force on the HALFEN T-head bolt in the connection HALFEN Curtain wall bracket to the HALFEN Cast-in channel, the design loads Fvd and Fhd at the connection between the curtain wall bracket and façade mullion can be multiplied with the factors sx, sy and sz. These factors depend on the bracket’s geometry, the load direction and the position of the bolt (see illustrations on the right). The multiplication factors to calculate the forces on the channel bolt can be found in the following table.
