In this paper, we will focus on the types of roof’s brick used
in construction and theoretically compare thermally between
different kinds in the local market, and finally we will propose a
new form of roof’s brick give the optimal insulation without
increasing the weight.
In this paper the effect of the distinctive properties of Shape Memory Alloy (SMA)
―the ability to undergo large deformation and restore it after stress removal‖ has been
studied to see to what degree it may affect the structural performance of mul
ti-storey tall
buildings.
Using ANSYS software, two 3D Finite Element (FE) models are built for a
composite multi-storey building (20 story) which is resistant to lateral loads by bracing
system. One of them is with steel bracing and the other is with SMA bracing. Both models
take into account nonlinear material properties of elements and geometric nonlinearity.
The model with SMA material shows improved performance compared with the
model of steel bracing in terms of residual deformations and ductile performance.
The study
will examine the effect of changing the diameter of the longitudinal
and lateral reinforcement on the carrying capacity of the concrete
columns and compare the value of the compressive strength of
concrete, which is associated with the theoretical relations provided
by (Mander), (Park et all) by building an analytical model using
finite element Program ANSYS.
