Create impressive effects on any type of channel, and even map them in 2D. Combine an unlimited number of effects with a Super Scene timeline.
Daslight 5
next generation DMX lighting software for PC and Mac
Probably the most powerful new feature in Daslight 5
Combine your different scenes on the timelines of a Super Scene and easily create complex and perfectly timed scenes with perfect precision. Change one of the source scenes and your Super Scene will be automatically updated.
Create impressive effects on any type of channel, and even map them in 2D. Combine an unlimited number of effects with a Super Scene timeline.
Control the dimmers of each group directly in the new Live mixer rack. Trigger the strobe, a blinder, change the colour... also from the Live mixer.
Control Dimmer, speed, phase shift, and size directly with the new live rotary encoders available for each scene. Play your scenes forwards, backwards, or both ways. Divide your scenes into segments which can be jumped between with a GO button or BPM.
Synchronize your show with the music BPM using tap-tempo, MIDI clock or Ableton Link. React to the music pulse with line-in audio. Divide scenes into a number of beats of your choice to sync in harmony with tricky tempo’s!
Switch the entire software to mapping mode, allowing you to link any control to your keyboard, MIDI controller, or DMX console in one click!
Set the maximum movement of your fixtures and focus the beams only in the area you want. Also adjust the minimum and maximum dimming of each fixture for your entire show.
Create a custom screen layout to use on a touchscreen, or link with an iPhone, iPad or Android device over WiFi. Perfect for mobile control and for installations.
Safety and Handling Handling heavy reinforcement involves ergonomic and safety concerns. CRSI highlights safe lifting, use of mechanical aids, avoidance of sharp ends, and protection of workers from trips and impalement. Bar ends should be capped or bent where necessary. Stable storage and staging areas prevent distortion and facilitate correct placement.
Special Conditions: Epoxy-Coated, Stainless, and Post-Tensioning Special reinforcement types introduce particular placing requirements. Epoxy-coated bars need gentle handling to avoid coating damage and may require increased embedment lengths. Stainless steel reinforcement and galvanized supports have specific connections and compatibility needs. In post-tensioned construction, placement of ducts, sheathings, and temporary supports for tendons must be coordinated carefully with rebar placement. Crsi Placing Reinforcing Bars.pdf
The Concrete Reinforcing Steel Institute (CRSI) publishes standards and best practices for placing reinforcing bars (rebar) that ensure reinforced concrete members meet structural, durability, and constructability requirements. Proper placing of reinforcing bars is critical to achieving design strength, preventing cracking, and ensuring long-term performance. This essay summarizes key principles, common procedures, and challenges associated with placing reinforcing bars per CRSI guidance, emphasizing practical considerations for contractors, inspectors, and engineers. Stable storage and staging areas prevent distortion and
Concrete Cover and Clearances Concrete cover—the distance from the outside face of concrete to the nearest reinforcement—protects steel from corrosion and fire, and ensures proper bond. CRSI reiterates that specified cover must be maintained using approved chairs, bolsters, spacers, and concrete blocks. Chairs and supports should be noncorrodible or epoxy-coated where required, and sized to resist displacement during concrete placement. Maintaining clearances between parallel bars and between bars and forms avoids congestion and ensures concrete consolidation around reinforcement. correct materials and supports
Conclusion Placing reinforcing bars per CRSI principles integrates careful planning, correct materials and supports, disciplined placing and tying practices, and thorough inspection. Attention to cover, splices, development, and sequencing reduces risk of structural deficiency and long-term durability problems. For contractors and inspectors, following these established practices improves constructability, reduces rework, and helps ensure that reinforced concrete structures perform as designed.
