P-Delta Analysis

P-delta is a geometric non-linear effect that occurs in structures that are subjected to compressive loads and lateral displacement. Under the action of compressive...

Second-Order Effects in Steel Structures

Second-order effects involve the analysis of a structure based on the deformed geometry. In other words, second-order analysis recognizes the deflection in a structure...

Design of Bridge Pier and Pier Cap

Bridge pier caps are horizontal structural members used for transferring bridge deck loads to the piers, before they are transferred to the foundation. They...

Natural Frequency Analysis of Multistorey Frames Using Staad Pro

https://youtu.be/dqxGIy9fcvo Vibration (or Oscillation) is a time-dependent, repeated motion which a body undergoes when it is excited in its natural state or by an external...

Modelling and Analysis of Imperfections in Portal Frames

Equivalent horizontal forces (EHF) are not strictly actions, but are forces that are applied to a frame in combination with other actions to model...

Structural Analysis of Portal Frames Subjected to Gravity Load

Gravity actions are normally used for verification of portal frames for lateral, buckling, and torsional stability. Elastic analysis and design of portal frames is...

Preliminary Plastic Analysis of Portal Frames

Steel portal frames provide economical solution for construction of industrial structures, warehouses, churches or other buildings with large enclosures. The loading scheme on portal...

Buckling Amplification Factor for Portal Frames Sensitive to 2nd Order Effects

In order to evaluate the sensitivity of a portal frame to 2nd order effects, the buckling amplification factor αcr has to be calculated. This calculation...
