The analysis of a framed building with shear walls subjected to horizontal and vertical load is essentially a three-dimensional problem. With the proliferation of computer programs available a three-dimensional analysis presents no great difficulty provided the modeling techniques fully reflect the behavior of the structure. The only penalty is time. Sometimes, especially where a dynamic(…)
Structural Analysis
PUNCHING SHEAR
What is punching shear? The failure mechanism of structural elements like slabs and foundation etc. by shear, is called punching shear.
BEHAVIOUR OF TENSION MEMBERS UNDER LOADS
Behaviour of tension members under the action of loads for tension ties and is discussed below: Behaviour of Tension Tie: The tie is the simplest type of member in tension. When a tensile load is applied on one side of a tie fixed at one end as shown in figure below, the applied load causes(…)
Finite Element Methods
The finite element method (FEM) (sometimes referred to as finite element analysis) is a numerical technique for finding approximate solutions of partial differential equations (PDE) as well as of integral equations. The solution approach is based either on eliminating the differential equation completely (steady state problems), or rendering the PDE into an approximating system of(…)
DEFLECTIONS IN DETERMINATE TRUSSES
DEFLECTIONS IN DETERMINATE TRUSSES Trusses comprise of members connected through pin joints. Truss members can thus transmit only axial forces (tensile and compressive forces). The basic difference in the behavior of a truss and a beam is that the truss comprises members that can sustain only axial forces but no bending moment or shear force(…)
STRENGTH EVALUATION OF CONCRETE BUILDINGS
Physical load test is required to determine the serviceability of the structure. Load arrangements, load intensity, loading criteria, instrumentation are explained.
FATIGUE STRENGTH OF RIVETED AND CORRODED STRUCTURES
The fatigue strength of riveted members is relatively insensitive to the rivet pattern or type of detail (cover plate details, longitudinal splice plates, and angles or shear-splice details). A major advantage of riveted (or bolted) members is that they are internally redundant. Cracking that propagates from a rivet hole is the typical phenomenon of fatigue(…)
DESIGN FOR TERRORIST ATTACK FOR NEW CONSTRUCTION
Site planning – Physical layout and physical security aspects are to be considered. Surveillance is to be provided for avoid terrorist attack. By providing access controls and physical barriers. By restricted parking near the building Deep buried structures are safer. Walls with soil cover on the side perform well under blast loading; soil is highly(…)
