З площини ферми розрахункову довжину стиснутих стержнів решітки приймають: для кутиків ферм lр= l; для ферм із замкнутих профілів з прикріпленням елементів решітки до поясів впритул lр = 0,9l
Стержні ферм повинні мати достатню жорсткість. Особливе значення має гнучкість l = lр/i для стиснутих стержнів. Навіть при незначних стискуючих зусиллях їх гнучкість не повинна бути дуже великою. Дуже гнучкі стержні легко викривлюються від випадкових впливів, провисають від власної ваги, вібрують при динамічних навантаженнях. Тому для стержневих ферм установлюють значення граничної, найбільшої гнучкості. Вони наведені у СНиП[2,табл.19*,20*].
