The prevalent theory of construction is a hindrance for innovation [PDF]

open access: yes, 2000
It is argued that construction innovation is significantly hindered by the prevalent theory of construction, which is implicit and deficient. There are three main mechanisms through which this hindrance is being caused.

Multiple injection techniques to stimulate complex fracture networks in coal reservoirs: A case study on gas disaster reduction of subsurface coal mine in southwest China

open access: yesDeep Underground Science and Engineering, EarlyView.
An experimental device for physical simulation of hydraulic fracturing, comprising: a load‐bearing mechanism with multiple interconnected plates that collectively form an sample chamber; a load‐generating mechanisms, with multiple load‐generating mechanisms arranged within the experimental chamber.

How Much Did the Liberty Shipbuilders Learn? New Evidence for an Old Case Study [PDF]

open access: yes
This paper uses previously unavailable historical records to show that several assumptions central to a learning by doing explanation of productivity growth in the construction of Liberty ships during World War II are mistaken.

Digital wood craft [PDF]

open access: yes, 2009
In 1995, Robin Evans points out in his book The Projective Cast how the development of techniques changed architecture and the space inhabited in times of Gothic and early Renaissance. We see a parallel phenomenon today, where the interplay of technology

Study on the composite fracture characteristics of filling and reinforcing cracked rock mass after high temperature damage

open access: yesDeep Underground Science and Engineering, EarlyView.
Cement infill shares compressive and shear stresses during loading, while interfacial friction hinders crack propagation and reduces stress concentration, improving the rock's load‐bearing capacity. Failure modes vary with crack inclination. Unfilled specimens show four modes.

Shock wave propagation characteristics of aluminum‐containing explosive in corrugated steel‐lined tunnel

open access: yesDeep Underground Science and Engineering, EarlyView.
Aluminum‐enhanced afterburning renders AE explosives more hazardous than conventional ones. Corrugated steel linings reduce far‐field AE blast overpressure by ~50% through wave reflection and dissipation. The developed model accurately predicts peak pressure (<10% error) and arrival time (<3% error), supporting protective design.

Prefabricated Building

open access: yes, 2015
With the continuous demand for construction of new buildings, an easier, more sustainable, energy-efficient and environmentally friendly building method is necessary to save time, energy and cost. Hence, there has been an increasing need for a system such as BROAD sustainable building (BSB).
