The focus of his work is on quantifying load effects caused by various natural hazards on structures and to develop innovative strategies to manage and mitigate their effects. The characterization and formulation of dynamic load effects due to wind, waves and earthquakes on tall buildings, long-span bridges, offshore structures and other structures is carried out via fundamental analytical computational methods, and experiments at  laboratory, and full-scale. He directs NatHaz Group (NatHaz Modeling Laboratory) which focuses on developments in cyberspace virtual collaborative research platforms, e.g.,  virtual organizations, crowdsourcing, computational intelligence, living laboratories, sensing and actuation, citizen sensing, web-enabled analysis and design, scientific machine learning (SciML) and cloud-based computing.

His fundamental contributions to aerodynamics and aeroelasticity has led to advances in the analysis, design and performance assessment of tall buildings and long span bridges, [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] high speed train aerodynamics, [13] [14] and land based and floating wind turbines. [15] [16] He has conducted from wind tunnel modeling [17] to stochastic and CFD (Computational Fluid Dynamics) [18] [19] based simulations and finally to the full-scale monitoring of some of the signature buildings [20] [21] around the world including more recently Burj Khalifa. [22] It utilizes a novel “SmartSync” system featuring “Internet-of-Things” (IoT) concept with built in layers of intelligence for data management and analysis. [23] [24] [25] He has advanced models for damping in tall buildings and motion mitigation devices like tuned liquid dampers from design, prototype testing to post installation monitoring in buildings in the US and in the Pacific-rim. [26] [27] [28] [29] [30] His contributions towards database assisted design through a web-portal recommended in ASCE 7 is used worldwide for designing tall buildings. [31] More recently, his group has embarked on shape optimization [32] [33] of tall buildings based on CFD with embedded topology optimization [34] [35] to configure efficient and optimal structural systems,super tall buildings and long span bridges. [36] He has developed prediction methods for quantifying hydrodynamic load effects and the attendant response of offshore structures under extreme environments and service loads. He has also contributed to a wide range of topics in the areas of offshore dynamics. [37]

He introduced the use of the Wavelet [38] [39] [40] and Shapelet [41] transforms to signal processing and feature extractions and advanced the use of Volterra systems, POD, ICA, PCA and DMD [42] [43] for data analysis and modeling.  He developed efficient simulation schemes for random vector processes: stationary/non-stationary; Gaussian/Non-Gaussian; Conditional/Un-Conditional utilizing spectral and time-series methods in conjunction with a novel scheme named “Stochastic Decomposition. [44] [45] He developed wind load models for non-synoptic winds like thunderstorms and downbursts and introduced the concept of Gust Front Factor [46] [47] and also developed models for hurricane wind field kinematics and dynamics. [48] [49] He developed safety and risk assessment schemes, [50] performance-based design approach for wind effects and impact of climate change. [51] In the area of Data Analytics and Machine Learning, he has contributed to data analytics, supervised, unsupervised and reinforcement learning; Bayesian Deep Convolution Neural Networks for random fields; Bayesian Deep learning; Dynamic Mode Decomposition; Surrogate Modeling with applications to structural engineering and dynamic loading; Digital Virtual Twins;  Fusion of CFD, Stochastics, Machine Learning and beyond; Autonomous morphing of structures through sensing, computations and actuation.

In 2009, Kareem was elected a member of the National Academy of Engineering for contributions to analyses and designs to account for wind effects on tall buildings, long-span bridges, and other structures. He currently serves as the President of the International Association for Wind Engineering. He was also the former President of the American Association for Wind Engineering. [59] [60]

<span class="mw-page-title-main">Seismic retrofit</span> Modification of existing structures to make them more resistant to seismic activity

Seismic retrofitting is the modification of existing structures to make them more resistant to seismic activity, ground motion, or soil failure due to earthquakes. With better understanding of seismic demand on structures and with recent experiences with large earthquakes near urban centers, the need of seismic retrofitting is well acknowledged. Prior to the introduction of modern seismic codes in the late 1960s for developed countries and late 1970s for many other parts of the world, many structures were designed without adequate detailing and reinforcement for seismic protection. In view of the imminent problem, various research work has been carried out. State-of-the-art technical guidelines for seismic assessment, retrofit and rehabilitation have been published around the world – such as the ASCE-SEI 41 and the New Zealand Society for Earthquake Engineering (NZSEE)'s guidelines. These codes must be regularly updated; the 1994 Northridge earthquake brought to light the brittleness of welded steel frames, for example.

<span class="mw-page-title-main">Wind engineering</span> Study of the effects of wind on natural and built environments

Wind engineering is a subset of mechanical engineering, structural engineering, meteorology, and applied physics that analyzes the effects of wind in the natural and the built environment and studies the possible damage, inconvenience or benefits which may result from wind. In the field of engineering it includes strong winds, which may cause discomfort, as well as extreme winds, such as in a tornado, hurricane or heavy storm, which may cause widespread destruction. In the fields of wind energy and air pollution it also includes low and moderate winds as these are relevant to electricity production and dispersion of contaminants.

The applied element method (AEM) is a numerical analysis used in predicting the continuum and discrete behavior of structures. The modeling method in AEM adopts the concept of discrete cracking allowing it to automatically track structural collapse behavior passing through all stages of loading: elastic, crack initiation and propagation in tension-weak materials, reinforcement yield, element separation, element contact and collision, as well as collision with the ground and adjacent structures.

The Eigensystem realization algorithm (ERA) is a system identification technique popular in civil engineering, in particular in structural health monitoring. ERA can be used as a modal analysis technique and generates a system realization using the time domain response (multi-)input and (multi-)output data. The ERA was proposed by Juang and Pappa and has been used for system identification of aerospace structures such as the Galileo spacecraft, turbines, civil structures and many other type of systems.

Lumped damage mechanics or LDM is a branch of structural mechanics that is concerned with the analysis of frame structures. It is based on continuum damage mechanics and fracture mechanics. It combines the ideas of these theories with the concept of plastic hinge LDM can be defined as the fracture mechanics of complex structural systems. In the models of LDM, cracking or local buckling as well as plasticity are lumped at the inelastic hinges. As in continuum damage mechanics, LDM uses state variables to represent the effects of damage on the remaining stiffness and strength of the frame structure. In reinforced concrete structures, the damage state variable quantifies the crack density in the plastic hinge zone; in unreinforced concrete components and steel beams, it is a dimensionless measure of the crack surface; in tubular steel elements, the damage variable measures the degree of local buckling The LDM evolution laws can be derived from continuum damage mechanics or fracture mechanics. In the latter case, concepts such as the energy release rate or the stress intensity factor of a plastic hinge are introduced. LDM allows for the numerical simulation of the collapse of complex structures with a fraction of the computational cost and human effort of its continuum mechanics counterparts. LDM is also a regularization procedure that eliminates the mesh-dependence phenomenon that is observed in structural analysis with local damage models. In addition, LDM method has been implemented in the finite element analysis of crack propagation of steel beam-to-column connections subjected to ultra-low cycle fatigue.
