Torsional effect of space structure in frequent earthquakes

Taking a concrete frame supporting space structure as the research object, we systematically studied its lateral-torsion coupling effect of reverse problems in consistent earthquake excitation. Firstly, based on its reverse forms and features, we put forward a mechanical analysis model (flexibility layer model) and a calculation method using the response spectrum method and the weighted average method, and verified their validity and feasibility using case analysis. The result shows that the translation displacement change trend of the space structure is basically the same whether reverse exists in the supporting structure or not, but the supporting structure torsion has an effect on the displacement with a relative increase of 10?.

Teaching primary mathematics with challenging tasks: How should lessons be structured?

Engaging students in a challenging (cognitively demanding) task and launching a mathematics lesson with a task before instruction are two characteristics of a reform-oriented approach to mathematics instruction often considered together. The authors systematically contrasted teaching with challenging tasks using a task-first lesson structure with that of a discussion-first lesson structure to three composite classes of first- and second-grade students (n = 73). Subsequent assessments of mathematical performance revealed that the discussion-first lesson structure was somewhat more efficacious in improving fluency performance but both structures similarly improved problem-solving performance. The findings suggest there is more than one way of incorporating challenging tasks into mathematics lessons to produce sizeable learning gains.
