משוך בקור בקירות במרחב מוגן

שלום רב,
למה אסור השימוש בברזל משוך בקור במרחב מוגן?
תודה

פלדת זיון למרחב מוגן

אופיר שלום.

רשת מעורגלת בחם מסוג פ-400 מתארכת בשבר במתיחה בשיעור של 12%.
רשת משוכה בקר מסוג פ-500 מתארכת בשבר רק בשיעור של 7%.

קירות במרחבים מוגנים נועדו לספוג עומסים דינמיים ע"י אובדן אנרגיה,
לכן חשובה לנו תכונת המשיכות בקירות.
רשת שמגיעה לכניעה בשלב מוקדם יותר אבל עדיין תמשיך לספוג אנרגיה ע"י דפורמציה לפני שתיקרע
תספוג סך הכל יותר אנרגיה לעומת רשת שתיכנע בכוח גבוה יותר אבל גם תיקרע מוקדם יותר.
