Wind and Seismic Analysis_Type of Structures and Structure's Form
- 1. Lecture 1 Structural Systems (Wind & Seismic Analysis) Ghanshyam Gupta Department of Civil Engineering Engineering College, Jhalawar
- 2. Outline of Module on Structural Systems • Introduction • Type of Structures and Structure’s Form • Aspect Ratio • Overturning Resistance • Strength and Stiffness
- 3. Introduction • The term structural system or structural frame is refers to the load resisting sub system of a building or object. • The structural system transfers loads through interconnected elements or members. • The structural systems or structural frames can be defined as the assembly of inter –related or inter- dependent elements which forms a complex structures, and they are designed and built for resisting different loads.
- 4. Types of Structural and structural forms • Load Bearing Systems • Framed Systems • Shell Systems • Strut and Tie
- 5. Load Bearing Systems • It is a structural system where loads of buildings i.e. weight of building itself plus the live loads get transferred to the ground through walls. Walls bear the load of roofs, floor and of course self weight. Theconstructor.org
- 6. Framed Structural Systems • Frame structures are the structures having the combination of beam, column and slab to resist the lateral and gravity loads. These structures are usually used to overcome the large moments developing due to the applied loading. • Framed Structures Can be differentiated into: Rigid Framed Structure i. Pin Ended ii. Fixed Ended Braced Framed Structures i. Gable Frame ii. Portal Frame

Difference between Load Bearing Structures & Framed Structures Load Bearing Structures Framed Structures Components Heavy Masonry Walls of Brick & Stone Beams, Columns & Slab Load Transfer Path Slab to Walls & Walls to Load Bearing Footing i.e Soil Slab to Beams, Beams to Columns & Than Columns to Footing Resistance to earthquake Poor Resistant More resistant Thickness of Wall Walls are Thicker Walls are Thinner Carpet Area Less Available More Available Speed of Construction Less More Material required More Material Intensive Less Material Intensive
