the present study sets out to integrate the performance-based seismic design approach with the connection topology optimization method. performance-based connection topology optimization concept aims to simultaneously optimize the size of members and the type of connections with respect to the framework of performance-based seismic design. this new optimization concept is carried out for unbrac...

A steel frame with a semi-rigid connection is one of the most widely used structural systems in modern construction. These are cheap to make, require less time construct and offer highest quality reliable construction without need for highly skilled workers. However, these show greater natural periods compared their perfectly rigid counterparts. This causes building attract low loads during ear...

This research developed polymer grouts made from wastes such as fly ash, palm oil fuel and silica fume. The selected served an interlocking key between the StormPav covers a grout to seal gaps keys covers. Based on compressive strength workability of grouts, mix ratio resin ash = 1:1.00 was chosen grout, while 1:1.50 used form key. Mix ratios had 98.90 MPa 81.70 MPa, respectively, flexural 53.0...

Abstract This paper investigates the robustness of a 6‐storey corner‐supported Modular Steel Building (MSB) under notional ground floor corner column removal (i.e. alternate path method). The assessment following structural effects that were frequently ignored for sake simplicity in existing numerical modelling approaches: (1) semi‐rigidity beam‐to‐column connections, and (2) initial out‐of‐str...

We characterize provability in intuitionistic logic with equality in terms of a constraint calculus. This characterization uncovers close connections between provability in intuitionistic logic with equality and solutions to simultaneous rigid E-uniication. We show that the problem of existence of a sequent proof with a given skeleton is polynomial-time equivalent to simultaneous rigid E-uniiab...

The existence and (non-)uniqueness of rigid multibody problems with impact, contact and friction is discussed by means of the renowned Painlevé paradox. Different approaches to solve such contact problems, their pros and cons and their connections are discussed.
