Abstract :

<p>&nbsp;<span style="font-family: &quot;Times New Roman&quot;, serif; font-size: 14pt; text-align: justify;">This paper deals with the analysis of steel building frame with one, two, &amp; three bays under the effect of dead load, live load, &amp; lateral load(EQ). According to IS 800:2007(appendix-f) Frey-Morris polynomial model is used for determination of secant stiffness (rotational stiffness) of different connection like single web angle connection, double web angle connection, top &amp; seat angle connection with or without stiffener, header plate connection, &amp; t-stub connection which is required for analysis of semi-rigid steel frame. Value of rotational stiffness is incorporated in analysis of steel frame using STAAD. Pro in place of assumption of rigid &amp; ideal pinned condition. Analysis results in terms of parameter like shear force, bending moments, axial force in the member, top storey displacement, weight of frame, time period for rigid &amp; pinned connection have been compared with corresponding results for various semi-rigid connections. Percentage rigidity of various types of connection in multi storey multi bay steel frames has also been determined in the present study.</span></p> <p class="MsoNormal" style="text-align:justify;line-height:normal;tab-stops:331.5pt"><span lang="EN-IN" style="font-size:14.0pt;font-family:&quot;Times New Roman&quot;,serif"><o:p></o:p></span></p>
