This paper examines the earthquake resistant design and construction practices prevailing in India. Results of a set of studies conducted to estimate the seismic performance of Indian housing stock, are presented. A field survey was conducted in the National Capital Region to assess the expected seismic performance of multistorey buildings, as these are so-called ‘engineered’ buildings and the ...

Airborne light detection and ranging (LiDAR) technology has become the mainstream data source in geosciences environmental sciences. Point cloud filtering is a prerequisite for almost all LiDAR-based applications. However, it challenging to select suitable algorithm handling high-density point clouds over complex landscapes. Therefore, determine an appropriate filter on specific environment, th...

Point clouds derived using structure from motion (SfM) algorithms unmanned aerial vehicles (UAVs) are increasingly used in civil engineering practice. This includes areas such as (vegetated) rock outcrops or faces above linear constructions (e.g., railways) where accurate terrain identification, i.e., ground filtering, is highly difficult but, at the same time, important for safety management. ...

The most commonly used analysis method in performance-based design (PBD) is nonlinear static (NSA). In unsymmetrical 2D frames, unlike for the symmetrical state, NSA should be performed two lateral loading directions. This complicates process of achieving a feasible optimal addition to increasing volume calculations. this study, overcoming issue, two-step approach proposed PBD steel moment-resi...

One of the typically damaged steel beam-column connection during the Northridge earthquake of 1994 was bolted-web, welded-flange (BWWF), now known as “pre-Northridge” connection. Proposed post-Northridge connections are more ductile and capable of dissipating more energy, thus improving the behavior of steel moment resisting frames (SMRF). The post-Northridge connections with added ductility wi...

Four design alternatives for lateral force-resisting systems of tall buildings in Dubai, UAE are presented. Quantitative comparisons between the different designs are also made. This paper is intended to provide different feasible lateral systems to be used in Dubai in light of the available seismic hazard studies of the UAE. The different lateral systems are chosen in conformance with the Inte...

Panel zone is one of the most important elements for transferring the lateral load to other elements in Steel Moment Resistant Frames. To some extent, this element through its suitable ductile behavior with beams, that themselves have been known as ductile elements, can increase the overall ductility of SMRF. The suitable design procedure for this element and details, can highly affect the perf...

The seismic design and assessment of steel moment resisting frames (SMRFs) rely heavily on drifts. It is unsurprising, therefore, that several simplified methods have been proposed to predict lateral deformations in SMRFs, ranging from the purely mechanics-based wholly data-driven, which aim alleviate structural engineer's burden conducting detailed nonlinear analyses either as part preliminary...
