Then after a semi - rigid joint behavior can be modeled as a finite stiffness rotation spring, base on rotation and displacement equation derive the element stiffness matrixes with semi - rigid connections where the effects of jointed flexibility and shear forces in the connection deformations have been considered in and fixed - end forces are modified. finally, a program for calculating system reliability of semi - ridge steel frames with monte carlo method and finite element analysis has compiled for calculating and analyzing. by calculating results of several examples for steel frame in semi - rigid joints case show the change of joint stiffness and other kinds of factors affect the system
接著本文在介紹和分析半剛性連接彎矩和轉角關系模型的基礎上，用帶有轉動剛度的彈簧表徵半剛性連接，推導出半剛性連接的剛度矩陣，對固端力進行修正，同時考慮了剪切變形的影響，編制了半剛接鋼結構平面框架的有限元程序bhpfl ，並在其基礎上編制了基於蒙特卡洛法的montecarlo - bhpfl有限元相結合的方法，進行體系可靠度的分析。
