The dual-airflow window could be used to conserve energy and improve indoor air quality in buildings because it works like a heat exchanger and can introduce outdoor air into buildings. In order to optimize the window design, this investigation used the orthogonal method to evaluate the importance of these 13 design parameters of the dual airflow window in energy conservation: outdoor air suppl...

Response modification factor (R-factor) is one of the seismic design parameters to consider nonlinear performance of building structures during strong earthquake. Relying on this, many seismic design codes led to reduce earthquake loads imposed to the structure. The present paper tries to evaluate the R-factors of conventional concentric braced frames (CBFs) and special moment frames (MRFs) in ...

The seismic response of two tall steel moment frame buildings and their variants is explored through parametric nonlinear analysis using idealized sawtooth-like ground velocity waveforms, with a characteristic period (T ), amplitude (peak ground velocity, PGV ), and duration (number of cycles, N ). Collapse-level response is induced only by long-period, moderate to large PGV ground excitation. ...

Truss structures are widely used in construction of large-scale buildings. Design of steel structures is standardised in detail through set of European standards called EUROCODE. One of these standards, ENV 1993-1-8 deals with design of joints, but it does not cover the design of conical element for reduction of circular hollow section to the joint. Finite element method was used in this paper ...

Design tasks in structural engineering have always involved the use of constraints to formulate design requirements. Most existing algorithms for constraint satisfaction require input consisting of binary constraints on variables that have discrete values. Such restrictions limit their use in structural engineering since typical structural design tasks involve discrete and numerical variables. ...

1 ABSTRACT: A risk monitoring of buildings for natural and man-made hazards mitigation is discussed in this paper. Ubiquitous monitoring using a network of wireless sensors is one of the most promising emerging technologies for this purpose. A smart sensor based on the “Berkeley Mote” platform was introduced, and application to the next generation of structural health monitoring and control was...
