New Release: RISACalc v4.1

RISA is pleased to announce the latest update of the web based software RISACalc. This version of RISACalc has added the following enhancements!

Hot Rolled Double Channels for Beams & Columns
Wind Load Generator (MWFRS)

The latest update to RISACalc includes wind load generation for the Main Wind Force Resisting System (MWFRS) with ASCE 7-16 and ASCE 7-10. Edit your wind load properties and site parameters in the easy to use tabs. Also update the building geometry to show in the graphic display of the Wind Load Generator. You can open the detailed report to view your results!

Design of CFS Face-to-Face Channels & Tube Shapes in RISAFloor

RISAFloor Version 16 now includes the analysis and design of CFS face-to-face channels and tube shapes. The Shape Selection dialog will allow you to select CS or CU Shapes with the added designation “F-to-F” for built up shapes. Tubes may be selected as an Explicit Shape. Face-to-face columns will display showing a closed cross section in floor plan views, and both columns and beams will be rendered in the Full Model view: There are a variety of code checks for closed shape sections per AISI code which are now included and performed during the design. One important parameter specific to the built-up shapes is the required definition of the value of “a” which is the spacing of the connections between the face-to-face members. This value is utilized to properly calculate the slenderness (KL/r) of the member and is required to receive a code check for any face-to-face cold-formed member. This additional spacing input is listed in Columns or Beams spreadsheet: Columns Beams Note that a value of N/A is automatically applied to single section shapes. With design complete, the detail report for face-to-face members shows all the controlling section properties including Effective Area, Section Modulus, and Moment of Inertia. For…

Women in Construction Week: Ruth Gordon Schnapp

Women in Construction Week is an annual event that takes place during the first full week of March. This week-long event celebrates women in the construction industry and their contributions to the field. The event was established by the National Association of Women in Construction (NAWIC) in 1953 to promote awareness of the opportunities available to women in the construction industry and to encourage women to pursue careers in construction. During Women in Construction Week, various events and activities are organized to celebrate and promote women in the industry. These may include networking events, educational workshops, panel discussions, job fairs, and community service projects. The goal is to raise awareness of the challenges and opportunities that women face in the construction industry and to encourage more women to pursue careers in this field. The construction industry has historically been male-dominated, but women are making strides to break down barriers and become more involved in this field. Women in Construction Week is an important event that recognizes the contributions of women in the construction industry and encourages others to follow in their footsteps.
